I was treating my daughter-in-laws to birthday pedicures, so it was a special outing for us. We were scheduled at the same time and next to each other, which was nice. Technicians were talkative, we all enjoyed the experience. At one point, we were asked if we'd like something to drink, one of choices was mimosa's which we each had. At check out, I was surprised to have been charged for the mimosas. I wish that had been made clear. I also wonder if a spa can charge for alcoholic drinks?
