Etiquette in mahjong
The game also offers some guidelines on game etiquette. Not necessarily enforceable via the games rules, they are still important to maintain a positive game environment. Depending on the decorum, the level of etiquette may vary given different environments and settings. Professional mahjong settings require very high level etiquette standards. In contrast, casual games among friends may be played with lower levels of etiquette.
