This subject comes up occasionally in other threads; I think it deserves a thread of its own.
I haven't been to Las Vegas for several years, and base my opinion on what I saw then; if things have changed I am unaware of it.
In the past one thing that always pissed me off about Las Vegas casinos was the lack of self-serve beverage stations; hell it's the middle of the desert, people get damned thirsty.
Not even a convenient water fountain.
Which leaves the CW's.
Why should anyone tip a CW to bring them a glass of water, when the water should be readily available and not require the employment of a CW?
As for maids I never leave them a tip: why should I?
I may tip a craps crew if I am doing well, but that is sort of like throwing bread in the water: I've had several times where after tipping them the crew "forgets" to take my bet down and leaves it up when it should come down (e.g. on a crowded table).
So far as tipping for a slot handpay: don't bother; do they tip you when you lose?
I understand AP's have a rep for being tight due to their reluctance to tip: again, why should they tip?
They're at work, and money given away means less food on the table.
I can't end this without posting my favorite movie clip on the subject:
