I'm a being unreasonable ?
I went to out local spar for essentials (milk, pop, wine, tin of beans etc) and paid on a credit card. I was half expecting the lady to ask 'would you like a bag'... but no, she just stood there and stared, so I asked 'can I have a bag please'. She replies: 'they cost now, 3p each' (in a less than friendly tone).
I would have thought that she should have asked if I would like to have bought a couple of bags (which I wouldn't have minded doing) BEFORE I pay on a card because I'm out of cash (and therefore using a credit card).
I ended up carrying everything to the car in my two arms and had to pretty much juggle it all as I unlocked car.
Normally I'm not a petty person, but this really 'gave me the 'ump' !
