The approach was poor for sure IMO. But....if a server sees a usual diner from their area who is dining often elsewhere, wouldn't it be ok to ask if something was missing in their service, the food is not to their liking, or what can we do to rectify? The up-shoot of this is the server is most likely paid his grats by how many he serves each dining period. This may be lost wages to him/her. Too bad this server didn't have the social skills to approach in such a way it wouldn't be offensive. We had a similar experience in Luminae....not impressed with the menu and dined in specialty restaurants often. At breakfast we were approached, in a nice way, asking us if we were visiting them this evening and what could they offer (me in particular) to entice us back more regularly. We weren't offended at all.
