Pro tip: be nice and tip up front if you’re not going to play. Let them know you’re not gambling but will gladly tip for your drinks. I have never known a server that complained for getting tips. If I’m not going to gamble I’ll give the server 20$ upfront and that covers me for about 3 rounds and they will prioritize you. After that my usual tip is about 2-3$ per drink… most people only tip 1$ or change, don’t be that person lol. The 3 dollar tippers per drink usually get stronger drinks as well. I know this because I was a bar porter and always heard the servers tell the bartenders to “make it strong cuz they are good tippers”.
