Restraunts should just charge the amount that is needed to pay their waitstaff properly, instead of relying on a tip and make their prices look cheaper! A tip is supposed to be extra money given the the waitstaff for services above and beyond the call of duty.
At least for me. Waiting was the easiest job with the most reward for the least amount of work. Tax free in some cases because it was cash.
Our job was to essentially walk from one side of the restaurant to the other side of the restaurant and meet drunk hot chicks. And they give you typically 10-30 dollars cash for doing so.
Hard work is standing behind a hot grill for $5-8 a hour, 10 hours a day without the tips.
That's fine in an ideal world, but in the United States that's not how eating out is handled. A tip is the payment to the waitress for her services while occupying a chair in her or his section in the restaurant. If you find this unacceptable, there are McDonalds Restaurants down most streets.
