Ha had this the other day, got to the till expecting to pay about X, cashier asks for amount X + shareholders yacht fund unless I produce a special card from my wallet. Forgot that I had it on my phone, so just left pretty much everything at the till, felt like a cunt, but also they are the cunts.
Tesco warning: their Finest ones are on special offer at £1 but you’ll need a Clubcard. Cunts.
Edit: not you, them. They’re cunts.
