Ok so was at the shop got a few items under £3 total phone wouldn't beep for contactless, didn't have my card, had put in voucher couldn't work out why it wasn't working. Staff member (male) paid for it, very grateful. Had tried to phone partner to bring my card down (live up the road from the shop) he hadn't answered. Got home and explained and he's got offended at 'some man buying your shopping' was ranting about go pay it back (no change on me) but is it just me or is he massively over reacting?
