I was at the Silverton playing bartop VP and they wanted me playing at least $1 per hand to get a comped drink. I understand where they are coming from though. If they don't enforce the minimum amount of play then they will get someone in there slow playing VP at 25 cents a hand and downing drinks like crazy. I have found that sometimes it is all up to the the bartender's descretion. Some bartenders will sweat your play while other's could care less (especially if tipping). I enjoy the heck out of getting to try all the different beers on tap and not having to worry about how much the drinks cost while playing bartop VP. The absolute best place I EVER played bartop VP was at Pub 365 at the Tuscany Casino. Good Lord they comped just about anything as long as you were playing and they had 50 beers on tap. I was drinking a different beer every 15 minutes for over 2 hours and I don't remember much after leaving. Sadly, they don't comp for bartop VP play anymore.
