I don't think this is a reflection of their entire staff, since I know they are out sources, but man, you guys should really screen your bartenders you hire. A cheery disposition is kinda suppose to be a bartenders MO (especially at a private Christmas party) Last night I experienced a up tight grinch of a bartender, with the biggest attitude ever. I was so taken a back by her lack of basic people skills, that I'm laying in bed the next morning, being forced to write a review.
Maybe next time, screen your bartenders a little better because they are a reflection of your company - and I will never hire pour masters because of this.
