Which downtown casinos are best for comp'd drink doubles? I know generous tipping can work wonders. And if I'm paying full price for my drinks at the bar I can get triples, quadruples, or any amount but I was curious as to which downtown casinos allows double drinks on comps. I ask because while I was playing keno at the bar at Downtown Grand this past Sunday night a guy who was sitting next to me and playing a machine as well asked the bartender for a double but was declined. Maybe the guy didn't tip well so the bartender refused his request. Or maybe the guy wasn't playing enough for a comp'd drink. I'm not sure what the reason was for the declined double request but maybe on comp'd drinks only a single can be ordered at a time. Any advice on how to get a comp'd drink double?
