I better confine my comments here, I've a sneaky feeling I know who that pilot was. And flight crew are humans and consequently encompass quite a span of their qualities. Hopefully that doesn't come as too much of a shock. There are some flight crew who cabin crew know to avoid, or limit social interactions, and there are some CSDs and CSMs who try their best to ensure that certain flight crew have as little inter-action with customers as possible, other than via the squawk box. Pilots aren't primarily employed for their customer service skills. That in no way interferes with their professionalism as pilots, you will hear comments like "he's appalling with customers, but if there was real trouble he's the one I would want up front" - and in any case these are the exceptions, there are many flight crew members who are held in high esteem by the cabin crew. There again, we all have a bad day sometimes, and some passengers don't half dilly dally.

Still, I would feed back. If you get a Tell-BA survey, some of them ask about flight crew.
