In town today, waiting to be served in a clothes shop. When a mother and her (about) 2 year old joined the queue behind me. The 2 year old was in a buggy but not strapped in.
The child then started to fuss and try to get out of the buggy when it tipped backwards. The mother shouted at the child (Called her a fu*ing bi*h) and really manhandled her back up and into the pushchair. This happened a couple of times and the mother's language and behaviour got worse. A man (who I assume was the father) came and tried to get the child to sit in the pushchair as well, he wasn't too bad at first, but then did quite rough with her as well.
In the end, the mother threw her clothes down, saying 'She's effing put me off buying anything at all now' And went and waited outside the shop for her other half.
Everyone in the shop seemed shocked (lots of glances at each other etc) and I really wanted to say something, or intervene. But I didn't.
Should I have? WOuld you have? Dp said if I had I probably would have got a slap, and wouldn't have changed anything for the little girl.
