Hey all - A friend of mine owns a bistro in my neighborhood with incredible food. It is not cheap ($25+) for the upper eschelon entrees, without salad...anyway, I support his establishment as often as I can. He constantly offers groupons at essentially 50% off ($25 gets you $50).
Is it cool to use these in a friend's place? I essentially go there twice as often with these coupons as I could afford otherwise (and I don't always use them, just intermittently). When I have the groupons, I'll generally tip at least 50% of the prediscounted bill (say $25-$30 for the server or bartender if we chose to eat at the bar), so the staff is generously compensated.
Any of you owners? What say you?
