Tipping is a hard subject for most gamblers to stomach and for gambling experts to talk about.  The only gamblers that don’t mind talking about tipping are online gamblers, as this is one thing they never have to worry about.  With too many tips, you could easily turn your winning profession into a financially losing venture.   As a gambler, however, you shouldn’t view the casino as an office or gambling as your livelihood.  Most gamblers view gaming as a type of entertainment.  And when you tip a coat-check assistant, restaurant server, valet, or cashier at a favorite coffee shop, giving gratuities to the service employees you find in the casino is customary.
