tipping

The service industry put me through university as well. One thing I never do is leave a tip on a debit or credit card because here in Canada, the tax man tries to make service employees pay income tax on their tips. I find this really nasty, as sometimes there are no tips at all, or sometimes a 'regular' will bring you home baking or produce from their garden. A tip, in my mimd, is a gift from the patron that they can choose to give, or not. Tax THAT, Jack!!!!
I may pay by card, but make sure I have cash to leave a tip so there is no paper trail.
