You're allowed to ask
Dealers deal with first-timers constantly and most are happy to explain a game's basics if you're upfront that you're new — it's far better received than guessing and slowing down the table.
Tipping is part of the culture
Dealers, cocktail servers and valets are typically tipped, the same as elsewhere in U.S. hospitality — a small tip or a bet placed 'for the dealer' is a normal, appreciated gesture at table games, and cocktail servers bringing complimentary drinks to players are usually tipped per round.
Table game basics
Wait for a natural break to join a table rather than interrupting a hand, keep your phone off the felt at most tables, and handle chips with one hand at a time — small habits that signal you know your way around without needing to say so.
Nobody's actually watching you
The single biggest myth first-timers carry in is that everyone will notice a mistake. In reality, casino floors are loud, busy and full of people focused on their own game — a slow decision or a beginner question barely registers.
