If he runs it right (and has two tables) you better believe that's the only job he needs. He's doing well. He might work another job but he probably doesn't need to if he can keep the game going.
BTW what helped us is we had an older crowd. Down here most our players were retired. As a result we started by 2PM in the afternoon. That's nice. A lot of games down here now start in the evening, they don't rake nothing like we used to rake. By 8PM we've already dropped about a dime down the hatch.
