Why the croupier's ruling is final
One rule at the tables prompts more questions than any other: the croupier's ruling is final. It deserves a proper explanation, so here is one.
House rules
One voice at each table
Games of cards and wheels have always needed someone to keep the order. In a busy room with six tables, that person is the croupier. They hold the pace, announce the play, and keep the count, which is why their ruling on a hand is final for that hand.
It is not a question of power. A table in which every player may reopen every decision becomes noisy, slow and sour. A table with one voice stays calm, and calm is what guests come upstairs to find.

How it works in practice
A ruling is quick
When a question arises, the croupier states the ruling in a single sentence and the game moves on. There is no debate at the table. If a guest wants to know the reason, the croupier will give it afterwards, at the rail, once the hand is complete.
The floor manager is the appeal
Any guest who feels a ruling was wrong may ask for me. I listen, check with the croupier and with the table, and explain the outcome. I have changed a ruling only once, and it was a matter of a dropped card that had been seen by everyone but the person who dropped it.
Why it suits chips without value
Since nothing has a monetary value, there is nothing to dispute heatedly. A ruling that costs no one money is easier to accept, and the table can laugh about it afterwards. That is the great gift of playing for honour alone.
In all our evenings, I can count the serious disagreements on one hand. That is not luck. It is the result of one rule, kindly applied.
If you are still curious, ask a croupier at the rail. Every one of them enjoys the question, and none will mind being asked at a quiet moment. The rule is written on the sheet at the top of the stairs, and the sheet is there for everyone, including me.
