Bad service from the one restaurant we loved, what a disappointment!

The waitress we had, treated us well. However, upon our departure from the restaurant we were not treated in the same way as the other clients were being treated. We received no formal greeting as was happening to other clients. We were seated near the door and have evidence of this happening. When we asked about the treatment they gave us, the one waiter sarcastically said it’s because we were part of the furniture.
