I initially wrote this as an email but couldn’t find a contact email, so I’m copying and pasting here:

To whom it may concern,

I was a patron at your restaurant this evening (6/1/2024) and I wanted to reach out to make you aware of an incident I witnessed, as well as our experience with our server.

Our server’s name was Caroline, and from the moment we sat down and she introduced herself, it was clear to us that she was very unhappy and did not want to be there or to be serving us. There was such an air of misery around her that we contemplated leaving before we got our drinks and food. What was even more upsetting was that we witnessed her being extremely rude to one of her coworkers. I’m not sure of her name, but she was a young blonde woman. Caroline seemed to snap at the young woman and said “Are you going to do anything, or just stand there?” It made us feel very uncomfortable watching her treat a colleague like this, especially in front of paying customers. Due to Caroline’s behavior, we will not be returning to MainSail, which is a shame because the food was actually very good. I hope that the restaurant manager will take this matter seriously and discuss this incident with her.
