I work in a garage and frankly this sort of thing happens far too often. Dude comes to the counter after putting in £45 of Optimax and says he has no wallet, so I ask if there is anybody they can phone, as I can can take their card number over the phone. Before I've even finished the question I get "NO", ffs man try harder next time. Also at the moment shell gor rid of the chip and pin systems (coming back though) and the number of retards that aren't even using their own card is ridiculous. They even try to sign for it when the card says Mrs A Smith and its a bloke standing signing the name Alison. When I say why are you signing for it when its not your card, all I get is "but you should have chip and pin". NO, you should use your own money you tard.
