Thanks to everyone who advised me regarding how to proceed after my less than satisfactory experience at Lucques this week, and shared their own stories of wonderful, and less than wonderful, service there.
I emailed Mr. Fannin yesterday afternoon and summarized what I had put in my earlier post. I did not send a link to my post. I also blacked out the name of the server on my receipt. These were both conscious decisions to put the situation in front of them in a dispassionate way and see how they addressed it.
I was very pleased with the result. Jessica Goin (sister, mom?) returned my email within hours, in the midnight hour, and wrote a very hearfelt apology to me. She also offered to give us a gift certificate for two for a future visit. She did ask me for the name of the server, but it sounded like he was going to get asked a couple of questions rather than harassed and tossed into the street, so I provided it. I got the feeling that they were generally distressed by the situation and trying very hard not only to make it up to me but to prevent fimilar situations in the future with other diners.
Thank you all for convincing me that telling them was the right thing to do.
