Cheap players in LV

[mike4bmp]

I have a friend that is a poker dealer who moved to Las Vegas for a little while to work at the Wynn...he returned to Seattle after working in Vegas for about 2 months. He says tokes are not as good in the bigger Vegas poker rooms. He told me he once pushed a $4000 pot and did not get toked anything....
He told me that the middle limit games are even tighter in this regards...
Just wondering why this is....? Higher Chip denominations? Trying to get the most out of the winnings...i.e. being stingy?
At the same time while playing 3/6 and 4/8 live I know that many low limit players toke way too much...3 and sometimes 4 dollars a pot...even for small pots.
