Bob,

Let me see if I can clear this up for you.

The pit bosses are poor guides.
The cocktail waitresses are pour guides.
They are in the casino so that when you are playing blackjack and they ask if you would like a drink, you turn around smack into their tip cups and scream, "Somebody hit me!". The dealer does, you break (or bust if you prefer) and Neal pockets another roulette chip at the next table in the confusion.

It's very clear to me.
