I was just in the post office and there was a sign on the wall saying 'please do not use your mobile phone while the girls are serving you'.
There were 4 women working behind the glass, all aged between 40 and 60 I would say.
It makes me think of the 17th Century when a rich English household might have an adult black man servant and call him 'boy'.
Am I the only one who gets so bugged by things like this?
