Oh, trust me, go to a decent place, be a regular, tip decently (not even extravagantly), you absolutely get looked after. For instance, several of my usual lunch spots my usual fountain drink is often "water" on the bill.
Isn't that then stealing from the owner?
I just don't think of a way you can have tipping and it not create perverse incentives like that.
I've had similar experiences in all-inclusive resorts in Mexico and the Carribean where they stock your fridge. Leave a few bucks in the door of the fridge, it'll be overflowing. If you don't tip, you get the minimum. Tip the bell man well at the beginning of the trip, and every time you call the front desk things show up at your room real quick.
