Booing is the standard way for audiences to show their lack of appreciation for a sub-standard performer. But could the practice also be extended to other situations where you're not getting what you expect?
In a BBC News piece on the history of booing triggered by Amy Winehouse's recent shambolic performance in Belgrade, comedian Jenny Eclair argues that booing provides a constructive form of criticism and should be used elsewhere:
There should be more booing in shops and restaurants and places like that when when the service is bad. If you've had a poor breakfast in a hotel, you should put your knife and fork down and boo.
I don't like poor service, but I can't quite imagine myself booing at a really bad meal. Could you do it?
