A little etiquette on the felt table goes a long way. A degree of sociability goes even further when players share a space on the felt. Wins should be congratulated and losses should invite empathetic feedback. Foremostly, the proceedings should add up to a good time. No player should be a downer or cooler. A smart aleck is even worse; hecklers are quickly dispatched and even discharged from the casino if coplayers are noticeably bothered, especially women.
An important facet of roulette is reciprocation of the dealer’s respect for the player. Respect is a two-way street in any venue. The dealer is a paid professional. The dealer does not trick or mislead the player. In blackjack the player and house hit or stand — the game’s terms to freeze or ask for a card from the deck shoe — on a number. Losing players routinely hit when they should stand. Roulette is a game of chance as well, but more focused on betting patterns and for losing players it may sometimes be tough to put blame for their losses.
Nevertheless, winning players should tip the dealer adequately. Players on a hot streak should and usually treat both the dealer and cocktail waitress generously. Players on a downturn don’t need to tip and aren’t expected to. Tipping is a practice inspired by courtesy and not obligation.
