The staff might have been shorthanded. Based on prior experiences,this was unusual. There was a large crowd however and maybe this and perhaps some staff out with the flu might be one of a couple of understandable reasons for the lack of hospitality one expects from a place that is not known for taking just a little more than what it gives in win loss ratios. Given that it's a place where the most predictable odds are that you will leave weighing less than when you arrived, the absence of service personnel is disappointing, at least. I was playing for over an hour without a glimpse of a waiter/waitress close enough to notice my presence short of shooting off a rescue flare. This is just one more thing to consider in a place where the only guarantee is that the odds are you will lose your shirt if self control isn't in your nature.
