We went in on a Saturday night because we had a taste for margaritas. To our delight a flyer on the table advertised half-price margaritas in conjunction with their 10-year anniversary.
No, the waitress said, that's only on weekdays. Perhaps the information shouldn't be out on the table when it doesn't apply, we said. It's our information, and we can leave it on the table if we want, the waitress said.
So we walked out because that kind of rudeness is simply not acceptable. Nor will we be patronizing this establishment again.
