Minor sitting at the bar
I like to meet with my college-age daughter once a week, and we've been meeting at various places in the area, one of which is the local Ruby Tuesday's restaurant. We like to sit at the bar. I'll have a beer, and she'll have cranberry juice as she is underage and doesn't drink anyway. On our last visit a new bar tender told us that it was illegal for her to sit at the bar. She's 19. Ironically, she works as a bar tender. We were reseated in the lounge area, and I asked our server if it was house policy or the law that my daughter couldn't be at the bar, and she came with that it was the law. Is this right?
