Couldn't agree more! ^ ^
From Merriam-Webster Online Dictionary:
Main Entry: tip, Function: noun: a gift or a sum of money tendered for a service performed or anticipated: see GRATUITY
Main Entry: gra·tu·ity, Function: noun: something given
voluntarily or beyond obligation usually for some service
Otherwise it's called wages/salary/rip-off!
