While you sound like a reasonable person, unfortunately, as others have pointed out, your colleagues in the friendly skies aren't, by & large. I've been hip-checked out of the way myself, even under the exact same circumstances as the OP (only person going thru the line) & then had to stand there twiddling my thumbs while I wait for the crew 'who are used to it' unload everything but the kitchen sink from their various pockets & then remove watches, cellphones, beepers, & all the rest of their electronic doo dads-seems to me that someone 'who is used to it' would have stashed all that stuff IN their carryon before ever heading out to the airport.

If I can do it, no reason why flight crews can't do it, too!
