Britain’s pettiest moments revealed: M&S versus Aldi’s caterpillar cake feud takes the crown
A survey of 2,000 UK adults has named the M&S and Aldi caterpillar cake battle as Britain’s greatest petty pop culture moment, while one in five people admits to being petty themselves.
Britain may pride itself on stiff upper lips and good manners, but new research suggests we are also a nation of people quietly keeping score.
A survey of 2,000 UK adults found that 21% openly describe themselves as petty. Among people aged 18 to 29, that rises to 38%.
The research was commissioned by stand-up comedian and broadcaster Vix Leyton for Chief Petty Officer, her comedy lecture exploring history’s greatest grudges, acts of revenge and spectacular overreactions.
Participants were also asked to choose the greatest petty moments in recent British pop culture. From caterpillar-shaped cakes and celebrity court cases to protest votes and Christmas chart campaigns, the results reveal the grudges, rebellions and beautifully unnecessary escalations that have captured the country’s imagination.
What is Britain’s pettiest pop culture moment?
The legal battle between M&S and Aldi over their rival caterpillar cakes was named Britain’s greatest recent petty moment, selected by 32% of respondents.
It finished ahead of the Wagatha Christie trial, chosen by 26%, and Meghan and Harry’s interview with Oprah Winfrey, selected by 21%.
Britain’s top 10 petty pop culture moments
M&S versus Aldi’s caterpillar cakes - 32%
The Wagatha Christie trial - 26%
Meghan and Harry’s Oprah interview - 21%
Boaty McBoatface - 15%
“What a sad little life, Jane” from Come Dine With Me - 14%
Sam Smith’s pub smart-device ban - 12%
The Rage Against the Machine Christmas number one campaign - 11%
Wetherspoons’ Brexit drinks decision - 11%
Lorraine Kelly versus the attendance tracker - 10%
Other acts of nationally significant score-settling - proving Britain is not short of candidates
The caterpillar cake dispute began after M&S took legal action over similarities between its Colin the Caterpillar cake and Aldi’s Cuthbert the Caterpillar.
What followed was not simply a disagreement about chocolate sponge. It became a national spectacle, fuelled by social media posts, brand jokes and an audience increasingly invested in the fate of two supermarket caterpillars.
For Leyton, it is a near-perfect example of a small grievance becoming culturally enormous once other people are invited to watch.
Why was M&S versus Aldi considered so petty?
In Chief Petty Officer, Leyton assesses grievances using the Hill To Die On scale, a comic framework designed to answer one central question: was the satisfaction gained from escalating the dispute worth the cost?
The M&S and Aldi feud scores highly because the original issue was comparatively small, but the escalation was public, prolonged and enormously entertaining to everyone outside it.
It also illustrates one of the central ideas behind the show: pettiness becomes significantly more powerful when it has an audience.
A private grudge can ruin an afternoon. A public grudge, handled correctly, can become a marketing campaign, a newspaper headline or part of British folklore.
Wagatha Christie remains a high point of British pettiness
The Wagatha Christie trial was selected by 26% of respondents, placing it second in Britain’s petty pop culture hall of fame.
The saga began when Coleen Rooney publicly described the elaborate process she had used to identify the source of stories being shared from her private Instagram account.
Her conclusion, delivered after months of carefully restricting who could see fabricated posts, became one of the most recognisable social media statements of its era.
The resulting libel case transformed a personal dispute into a national event involving courtroom reporting, forensic social media analysis and an audience eagerly following every development.
For Leyton, Wagatha Christie demonstrates that the most satisfying petty acts often require patience.
Some are caused by a split-second loss of restraint. Others need planning, evidence and the willingness to construct an entire private intelligence operation because somebody has annoyed you.
“What a sad little life, Jane” lives on
Peter Marsh’s Come Dine With Me declaration, “What a sad little life, Jane”, was chosen by 14% of respondents overall.
Its popularity rose to 23% among 18 to 29-year-olds, showing the extraordinary afterlife the moment has enjoyed through memes and social media clips.
The speech remains memorable because of the vast difference between the occasion and the response. What should have been a relatively low-stakes dinner-party competition ended with a monologue delivered with the gravity of a defeated monarch addressing the nation.
That mismatch between the size of the grievance and the scale of the reaction is one of the foundations of great pettiness.
Which UK city is the pettiest?
Glasgow emerged as Britain’s most self-confessed petty city, with 30% of residents surveyed describing themselves as petty.
Cardiff followed at 27%, with London in third place at 26%.
The UK’s pettiest cities
Glasgow - 30%
Cardiff - 27%
London - 26%
Swansea - 25%
Plymouth - 24%
Leeds - 23%
Manchester - 23%
Newcastle upon Tyne - 22%
Birmingham - 21%
Edinburgh - 21%
At the other end of the table, Belfast and Aberdeen were the least likely to embrace the label, with 9% of respondents in each city identifying as petty.
They were followed by Sunderland at 11% and York at 12%.
Whether this means those cities are genuinely more forgiving, or simply less willing to admit what they have done, remains beyond the scope of the research.
Why are people petty?
Leyton argues that pettiness is not simply a character flaw. It can be driven by pride, identity, frustration and a desire to regain control when more conventional routes have failed.
“The more I’ve researched pettiness, the more it feels like an under-acknowledged driver of culture,” she says.
“These aren’t just silly moments. They are stories about pride, identity and people refusing to let something go.
“Some petty acts are surprisingly revolutionary, while others, like Boaty McBoatface, are pure mischief. For me, it is inspirational, for better or for worse.
“And for the 79% of people who claim not to be petty, I see you.”
A petty act can be destructive, but it can also be an effective way of attracting attention to a genuine problem.
Residents have held birthday parties for potholes, planted objects inside them and created elaborate displays to embarrass authorities into acting. The methods may look ridiculous, but the grievance behind them is often serious.
This tension sits at the heart of Chief Petty Officer. When someone feels ignored or powerless, a public act of pettiness can become an unconventional form of protest.
What is Chief Petty Officer about?
Chief Petty Officer is a visually driven stand-up comedy lecture created and performed by Vix Leyton.
The show investigates famous grudges and acts of score-settling from across history, politics, sport, music and popular culture.
Using the Hill To Die On scale, Leyton examines who executed the perfect petty act, who disastrously doubled down and what happens when a private grievance gains a public audience.
Stories explored during the development of the show have included:
The Wagatha Christie investigation
50 Cent buying seats at a rival’s concert
Rage Against the Machine’s battle for Christmas number one
David Beckham’s 1998 World Cup red card
Britain’s tradition of joke political candidates
Ea-Nasir and the world’s oldest known written customer complaint
Corporate and celebrity feuds that became far larger than the original insult
Part stand-up show, part history lesson and part forensic examination of human grievance, Chief Petty Officer makes the case that pettiness is one of history’s most overlooked motivating forces.
Who is Vix Leyton?
Vix Leyton is a stand-up comedian, broadcaster and consumer finance expert.
She has appeared across television and radio discussing consumer issues, using research, storytelling and humour to explain the behaviour of companies and the people challenging them.
That experience also makes her professionally familiar with the emotional consequences of disputed bills, unanswered complaints and refusing to let a company keep a few pounds simply because retrieving them would be inconvenient.
Chief Petty Officer is Leyton’s second solo comedy show and marks a move into visually driven comedy about history, culture and human behaviour.
The show is designed for audiences who enjoy intelligent stand-up, strange true stories and learning something unexpectedly useful while laughing.
It may particularly appeal to fans of BBC Radio 4 comedy, QI, You’re Dead to Me, No Such Thing As a Fish, history podcasts, pop culture analysis and anybody who has ever continued an argument long after it stopped being practical.
