Tipping over here is a coin in the jar and a nod, nobody's rent rides on it. But I've worked a summer in Boston same as you, and the lads on the floor were clearing $40 an hour on a Saturday. Go and ask them if they'd swap it for $18 flat. Some would. Most would laugh at you.

I waited tables in LA for three years before the internet thing. Saturdays were $40 an hour, yes. Tuesdays were $30 for the whole shift. And on both days I smiled at the man who grabbed my wrist, because the tip hadn't been written yet. People who say "most would laugh at you" are remembering Saturday.
