I was just about to enter Waitrose today and noticed this young child 3/4 year old crying and on his own, there wasn't an adult nearby looking over at him. I was just about to ask him if he was lost and then another lady went up to him and asked him if he was ok and took him to find his 'Mummy'. I went in to the shop afterwards and saw this woman had found her and handed him back. The Mum hadn't even noticed and didn't thank the woman, in fact she was very blasé about it.
AIbu in thinking she should've shown some gratitude or care even?
