Self-explanatory.... no? This could be another form of earning money on your venue from your visitors, since they might want order a drink or two. There could even be an option to assign a visitor to work on it, with the 'click sad or smile face' prompt.
Or at the very list act like one from TS2:Night Life: http://sims.wikia.com/wiki/Bar_(object) http://sims.wikia.com/wiki/Mixology_(The_Sims_3) http://sims.wikia.com/wiki/Mixology_(The_Sims_4)

The game already has bars, and an original game idea from Maxis was to make certain sims "Bar Tenders", like you are thinking of. I could see it kind of being fun on ENT lots/casinos.
Yeah, we need serving bars. It would add more diversity to the game. Being served is more fun than having to serve yourself. Sims should get drunk (fun boost and energy decrease).
