DH and I are part owners in a bar nearby. Although we serve food from an attached restaurant that is all ages, the actual bar is strictly 21 and over. We have a bouncer on Friday and Saturday nights to enforce this. My sister is aware of this policy, as I have mentioned it multiple times to her, and we have a cousin who is still a few months shy of her 21st birthday who desperately wants to see the place but can't yet (it's new, only open about a month).
So on Saturday I saw a facebook post on my sister's page. It was of her and a group of work friends at my bar the past weekend. It was a memorial because one of the girls had passed away. That girl was only 20. After giving my condolences to my sister over the loss of her friend/coworker, I asked how the girl got into the bar at 20 years old. She stated that it was probably a fake ID, but that it didn't matter because the girl passed away anyway. She was annoyed with me, which I get. . . . my timing wasn't great.
From a business perspective, however, I need to know these things to try to avoid serving to underages patrons in the future, god forbid something happens. I'm annoyed with my sister for bringing underage people into my bar. I feel like that's a big slap in the face. Would you be annoyed? With that being said, what can I even do about it?
