Tipping and Wages:
Should the minimum wage include tips for 'service' jobs? NO. Tips should be extra. I learned this a long time ago, in Europe. Wages were decent there, and the people doing a job which in the USA would be a tipped job, like waiting on tables and so on, were just as good and just as nice as the people doing those jobs in the USA. If you tipped service people in Europe, that was ok, but wasn't required for the worker to get a decent wage.
