Signed up to a store card, an incentive to do so was a large bag of Haribo, i accepted the Haribo even though i don't eat them (later gave them away to a family member). To process said Haribo, cashier scanned them, when she scanned them, she didn't give me them for free for having just signed up to a store card, she scanned them as if i'd wanted to buy them so it whacked £1.50 on the card!!! Having a letter through the post and having £1.50 mysteriously come up that i knew i hadn't spent spooked me and haven't spent anything on it since.... I'm now owed £1.50, won't get it back, that's alright, will never shop there ever again, simple
