depends on the game i hvent been to many recently but when i used to go to poker games at peoples houses man the person hosting would spend about 500 on food and drinks and stuff and make around 1500-2000 a night in profit just hosting, and the dealer takes a rake anyways and yeah if i won a very nice pot of a few hundred i throw him a 5 spot or so, but at the end of the night the dealer is still making close to 600 minimum sometimes up to 1200 dollars tax free on a 6-12 hour night with 20 or so people. i don tthink they need tips like a girl working at a casino who only gets paid hourly + her tips, they make enough lol, but yeah any nice hand throw ema 5 chip
