M&S emoloyee commits the ultimate betrayal by shopping in Aldi as The Traitors finale nears
As The Traitors reaches its tense finale week on BBC One, fans of the show - and Britain’s long-running Aldi vs M&S supermarket rivalry - have been left in stitches after an eagle-eyed shopper appeared to catch an M&S employee committing the ultimate act of betrayal.
The viral snap shows a Marks & Spencer staff member doing their weekly shop… in Aldi.
With The Traitors at peak paranoia - and viewers still reeling from Jessie’s shock murder to Friday’s intense round table - the moment was instantly branded a full-blown supermarket betrayal.
Just as Faithfuls and Traitors scramble to work out who’s bluffing on BBC One, shoppers are playing their own version of the game: who can stretch their weekly budget the furthest? And in that challenge, Aldi is the supermarket many shoppers trust - no cloak, no dagger, just consistently low prices.
Given the fierce rivalry and Aldi’s reputation as the UK’s cheapest supermarket, social media users joked that the employee had chosen Aldi’s prices over loyalty, quipping, “even with a staff discount, Aldi is cheaper than M&S”.
The image first circulated on X with the caption: “Ahem, @AldiUK. There seems to be a security issue in my local store.”
Never ones to miss a cultural moment - especially during The Traitors finale week - Aldi jumped straight in, resharing the post on Facebook with the caption: “Someone call Clauds, we’ve caught one ” - a nod to the show’s host, Claudia Winkleman.
The post struck a nerve, racking up more than 20K likes as shoppers flooded the comments. Some declared the employee was “deep behind enemy lines”, while others joked: “They’re not kidnapping Cuthbert, are they?”
One posted: “Traitor found in the biscuit aisle”
Another added: “Suspicious item in bagging area.”
While a third joked: “The Aldi security guard watching the M&S employee walk in…”
As if one public call-out wasn’t enough, Aldi also shared the post on Instagram, fanning the flames as The Traitors dominated the TV conversation in its final days.
With Aldi continuing to cheekily taunt its premium rival - and viewers still dissecting every betrayal, banishment, and bad call - fans have dubbed the crossover “priceless”.
Proof that whether it’s a Highland castle or the middle aisle, when budgets are under pressure and the truth comes out, even the most loyal can be tempted to switch sides.
