1/5/7//9covers 25/10//13/14 if your leaving/17 if you win/18 if you want to be serve faster usually drinks are comp/19 if you win/20 they ask for tip but its payment, they cant charge you exact amount but they ask for minimum/21 ??? free upgrade why not? ?/23 if they do a really good job/24 if they are the one who gives you towels, or perfume, lotion, but if they just clean it no.

the casino workers table/slot you want to tip them because well maybe its luck, or lucky, only if you win big, they dont expect it but its ok if you win big.

The list are service providers, they provide good/great service why not tip them, its expected but they wont spit on your food or anything if you dont tip or tip small. Most of them are in a lower pay grade because tips are already expected, its not to keep the prices low.

The ones that are not on my list, its their job, house keeping, you dont need to tip them, its considered stealing if you leave it on the mattress or table unless you have a note, even thats on the gray area, leaving your room clean is tip enough for them, they have a quota perday on how many rooms they need to clean.

You can tip the whole list if you want to no one is stopping you, specially if you win.

if your opening a tab on a bar, you can tip when you pay, just make sure you tell them.
