I always fuel up at Sainsbury’s & push the kiosk button & pay in there ( card ) , Think I have used Asda in Grantham on very odd occasion & there’s a kiosk there , x Amount of pumps for pay on pumps / x amount for pay at kiosk .
Cash , I can’t remember the last time I paid for anything by cash , do get mrs £30 cash for work , meals etc
Only thing I did notice the other week was the vouchers you got for double nectar points if you brought £30 worth of fuel at Sainsbury’s now stated £30 of super unleaded , but this week we’re back to £30 of fuel , so maybe a few moaned like me at customer services
