I took my daughter to a Ruths Chris for her birthday. The waitress had no idea what "Pittsburgh rare" was, brought us a salad we did not order (then she picked it up and took it to another table). We ordered an expensive bottle of wine for the occasion and she had no idea how to use the "french" wine opener. And she brought the wine about 10 min after the runner brought the meal - despite our asking for it on ordering and once more.
The bill came to about $350. I left no tip and wrote "terrible service" on the check. As I was leaving, my daughter not thinking I saw, gave the waitress a $100 bill I had given her for her birthday. I went back in and demanded it back from the waitress and had a talk with the manager (as well as my "knows everything" college daughter)
