I experienced the same being ignored at Pancho and Lefty's while they paid attention to the two other customers there in an almost empty restaurant - so I said to my son, " Let's go," and we left...that was like 5 years ago, and I haven't been back since. So this has been going on for quite a while.
The no ice is absolutely valid. Theres portions to drinks. No ice doesn’t mean you get more. If you order a drink at a bar no ice you’re not getting more liquor.
