I have played ALOT of VP at Sully's at Bally's. Most of the time I am either by myself or playing with hubbie who is also playing. But there have been numerous times where one of my kids or another travelling partner will join me for a bit, perhaps before dinner or something and the bartenders will most definately give them a drink and put the slip in my glass. It has never been an issue. Now, I would never expect them to comp a companion's drink all night, but a couple here and there has never been an issue, even top shelf. I agree with other posters, if you plan on being there awhile, either throw a $20 in her machine or run a tab for her. I have found many times running a tab for someone that doesn't atually know how to play VP is much cheaper in the long run. Have fun!
