The talk of tipping and making deals with waitresses for roulettes, makes me uncomfortable. You might get away with it for awhile, but I echo Jim P's post,
SOMEWHERE ALONG THE LINE, A WAITRESS WILL LOSE THEIR JOB.

Involving an employee in a practice that casinos frown on, can cost them dearly.

Again, I am not saying roulette chippers should not take roulettes, but it should not involve casino employees.
