First, I have to agree, tipping is a bizarre system/cultural norm, and I am very curious about how, historically, this came to be...<p>From my perspective, I spent a year working as a barista and bartender part-time when I first moved to New York, and I would estimate that 80% of those who work as a waiter, barista or bartender do it to support themselves as they pursue whatever it is they do (the usual suspects: acting, art, music, writing, school etc.). This is what kids do to get by--they're not committed in any way to the place they work.<p>At my coffee shop (not at restaurants or bars) I got paid minimum wage plus tips, which at the time was something like $8 + on average $4 to $8 an hour. I can't say I agreed or disagreed with the system at the time, or that I even thought about it, but from my experience the lure of tips greatly outweighed any set amount of (low) salary I would have received. For example, I've gotten a couple $100 tips from Wall St. ballers, or one time $40 from a man just for pouring a cup of coffee! If you work at any number of restaurants, the odds are much higher that on any given night, you will win the tip lottery. And the more a man drinks, the more he will open his heart (and wallet) to the young, struggling artist behind the bar.<p>For the waiter/bartender/barista, I would guess that the average wage comes out to about the same as a respectable working wage for the skills involved (maybe $15-$20/hr). If you work at a Michelin rated restaurant, you would have to get a much much higher starting salary to compensate for a lack of tips, at least in NYC.
