Haven't seen this mentioned elsewhere, so I'll post here as well as in my upcoming trip report. Aria has new rules regarding comping drinks at bartops in the casino: 1) Must have an mLife card in the machine. 2) Must start with at least $20. 3) Must play maxbet at all times. 4) One drink every 30 minutes. #1-3 are pretty standard for bartops, but #4 is pretty annoying for everyone. It is strictly enforced based on the timestamp on the receipt. Players don't like it because they're there to drink. Bartenders don't like it because they have to play bad cop. The bartenders I spoke with said it came down in the form of a memo from casino management, not food & beverage management. Being a memo it is grounds for dismissal if it is not adhered to. The bartenders are not optimistic it'll change because it is unlikely the complaints will get back to casino management. No word yet if this will spread to the other MGM properties.
