went out with friends Saturday night for a quick drink at a bar, we ordered one coffee, one beer, one coke, and one salad. Ok it was a bit of an odd order but one friend was hungry so she had the salad and a glass of tap.
The bill came and because she was paying for her own salad rather than just one of us paying for all the drinks we checked the bill to see how much her salad was and amazingly there was a margarita on the check which nobody had ordered.
We all agreed that had one of us just picked up the check we would probably not have noticed this extra charge - late Saturday night, outside bar, darkish. This drink for $9 would probably have snuck through. You know how it is, one person throws down his or her credit card after a quick glance.
Just goes to show it is worth checking the check carefully everywhere. Server was very matter of fact unapologetic and we wondered if it was a deliberate ploy.
