Seriously, the hospitality industry I would expect to show them a good time and a good value for their dollars.
Those guys throw down a lot of cash when they are out to party.
Around 20 years ago when my fist son was an infant and my wife was in law school, I bar tended at a gay bar in NYC.
Most customers would throw down $20-$50 tip for each round.
With that I was able to save our house from foreclosure, cover the cost of NYU Law and save money.
