ne of the best pieces of advice I was ever given was from a friend in the restaurant business. If I were planning to complain about any part of my meal or service, he said, I should wait until I had eaten all I was going to eat that night. He illustrated this warning with examples of what can happen to food prepared for awkward customers, and so I’ve followed this advice ever since. It’s a good principle: don’t complain to people on whom you’re relying – unless there’s no way they can wipe your steak on their bum or drop a bogey in your soup.
As with restaurants, so with schools. The difference with schools is that you’re likely to be stuck with them for a lot longer than one meal. So think carefully before putting on your Mr Angry face and marching into the school for a spot of ranting.
