Dealer's call

[redfisher]

To specifically answer your question, you are under no obligation to call. The dealer can't rule on jack. In all likelihood he knows the rules and is right, but you can call the floor at any time to get an actual ruling.

There's no reason to flame on a dealer because the house painted a betting line on the table. If you agree with me that painting a "betting" line on the tables means that its a commitment line, you're much better off giving what for to the management team versus a dealer.
