I made a very rare visit to a McDonalds 2 weeks ago, and a woman came in with her son, aged about 4-5. He started running amok within seconds. His mother was at the other end of the place, busy chatting to her friends.
But after about 5 mins, the inevitable happened and the little boy slipped and hit his head on a table. The mother then noticed that her little darling was yelling and accused the poor McDonalds worker of not cleaning up a drinks spill quick enough. Rather foolishly, I tried to come to the aid of the McDonalds lady, saying that the mother should have looked after her child, instead of gossiping at the other end of the place. I just got a lot of bad language, so wished I hadn't bothered.
