another tipping question (sorry)

[AaronO]

I play very little live poker, but when I do it's 1-3 NL at the Argosy in Indiana. Based on what I've observed, it seems that it is customary to tip the dealer after every hand regardless of pot size. Most all players even throw the dealer a dollar after taking the blinds uncontested. This just seems crazy to me, and I typically do not tip unless I win a significant pot.

Is this wrong of me? Should I be tipping every pot if everyone else is? If this has been covered in another thread I apologize, and would greatly appreciate a link to any relevant threads. Thanks.
