Dealer

A dealer was the person responsible for dealing playing cards during a game, and may be an employee of a casino.

A casino in the early-21st century novel Hotel Royale employed numerous croupiers. In 2365, the USS Enterprise (NCC-1701-D) encountered a planet, whose inhabitants had based themselves on the book. One of the dealers there oversaw a game of blackjack with Lieutenant Commander Data and a man named "Texas". 

Members of the senior staff of the Enterprise-D, as well as several junior officers and civilian waiters from Ten Forward, regularly played poker, a card game that requires a dealer. When Captain Picard joined the game in 2370, he was the dealer. 

In 2375, several holographic mobsters assumed control of Vic's lounge, Doctor Julian Bashir's holoprogram of a 20th century Las Vegas club. They immediately turned it into a casino, employing several dealers. When the senior staff of Deep Space 9 attempted to reclaim the casino for Vic, one of the dealers there was told by Frankie Eyes to give Kira Nerys several different cards after she busted in blackjack.
