Barber

I got my hair cut yesterday. One of the best things about going to a barbers' shop in America is that the chair you sit in is mounted on a turntable which allows it to be rotated through 360 degrees. So whereas in the UK, you sit facing the mirror while the hairdresser moves around you, in the US the hairdresser stays in the same place and swings you round as required. Not only does this save them the needless exertion of walking around the chair and squeezing into awkward positions to get at various bits of your head (and we know Americans don't like to walk any more than they have to), it also provides some mild excitement and variety of view for the customer. Everyone's a winner.
