I don't believe you were charged 7.22 for a haircut. £7 or £8 maybe. I pay £42. Don't smoke anymore, but the last time i looked it was over a fiver for a packet of cigs.
I once paid £60 odd pounds for a haircut that turned out to be disastrous.
I now pay £10...but that could be a special deal.
The cigarettes I bought recently to make me cough were about £7.
Years ago a friend in Canada used to send me B&H menthol cigs because they were so cheap over there. They came labelled toilet water for some reason...tax maybe....don't know but I was sorry when he came home.
