I'm still at a loss to understand why someone intelligent and successful enough to be able to afford to eat at a high-end restaurant would have the slightest interest in the views of a server as to the merits or otherwise of what's on the menu.

If a server steers a diner away from a particular dish then what is it doing on the menu in the first place ? And if a server ever gushes about a particular dish to me and I ask why the answer is almost invariably " I had it myself and it was great." Really ? I had liver and onions last night and it was really great but hey, not everyone is into offal or onions or gravy.

Over-bearing, presumptuous and intrusive are what really tick me off about some wait staff.
