There are a number of casinos in the eastern half of the US that have these stations also. I usually only drink soda or water when at the casino, so I prefer this setup to having to find a waitress or go to the bar to get something to drink. The ones that have it tend to be the more isolated locations with limited foot traffic. I don't think they'd work in Vegas since there are so many people just walking through the casinos and not necessarily playing.
