I've seen this behavior where ever I've played and I've played all over. I think it's the worst in LA. The dealers there get treated the worst of anyplace I've ever seen. I think players do this for a number of reasons, the blinds coming around being one of them, but it happens when I play stud also and there are no blinds there. I attribute it mostly to players who are usually unable to say anything about poker with authority and when they find something that they CAN comment on they do it.

I wait 5 minutes before I say anything to the dealer if I know there is a board and then I'll say something like "Do you know if a player has been sent?"
