I've just got home from doing a big shop at Lidl and am wondering what your take on the following situation is. I had done quite a bit of shopping (nearly filled a trolley) and was unpacking at the till. A lady came to wait behind me with a basket with only a few items in so I asked her if she'd like to go in front of me as it was taking me a while to unpack. She said thanks and went in front. I'd taken some reusable bags but had misjudged how many I'd need so had put three of their plastic bags at the front of my shopping. My turn came and the lad at the till starts ringing my shopping through when the lady who went ahead of me comes back to the till (I assume after looking at her receipt) and says she's been charged for three carrier bags. It turns out the lad on the till has put them through at the end of her shopping rather than at the start of mine. He apologises and explains he can refund but she'll have to wait as he's started ringing my shopping through. She turns to me and asks if I can pay her for them - 27p. I have a pound coin in my pocket but she has no change. Cue a bit of tutting and looking at her watch and an under the breath 'I really haven't got time for this!' I carried on sorting my shopping (and got the bags re-scanned) while she stood sighing until my transaction was finished. AIBU in thinking she could have let it go for the sake of 27p? I had let her go ahead of me which saved her a good five minutes in the queue which she then lost hanging around for her refund! Would you have bothered?
