To not tip anybody?

[goodbyemrschips]

A thread on tipping hairdressers made me think.

I do not tip anybody. Do you?

Do you tip the sainsburys checkout girl?

If not why not when you may tip the waiter, hairdresser or taxi driver?

I tip on the rare occasion I go out to eat is service is good. Don't tip hairdressers but am poor and only go once a yr usually.
