Wondering if I should have said something or just minded my own business.?Yesterday I was in McDonald’s with my son. We were at end of large long table, large group of mums and small kids came in. Three of the girls aged about 4/5 sat at our table. One of the girls was being quite mean to what seemed like a quieter girl. Quieter girl says one thing, mean girl starts crying and goes and tells mum. Quiet girls mum comes over and tells her off for not being nice. Quiet girl sits on floor looking very sad. Mum tells her off for sitting on floor, then when she won’t get up carry’s her off. Girls left discuss how quiet girl has been taken away to be told off and are very happy about it. Two boys come and sit at the table to play on the tablet. Girls are dipping their chips in ketchup and trying to wipe on the boys, boys slightly older and were just ignoring and trying to move out of way. Same girl then announces they are being mean and goes off to tell parents. We were then leaving anyway so I said nothing but it did annoy me, wondering if I should have said anything?
