I've seen one of the pilots come out to take a leak, then stand around in the galley chatting for a long period of time. On one occasion I had gotten up to go to the loo and the co-pilot came out, the cart came out, and there I stand (was in a window seat). And after he does his business, he doesn't go back in but I'm left standing there waiting to get into the toilet and he's having a good time chatting. Finally he goes back into the cockpit and the stewardess chastises me for standing there! It was both inconsiderate and also worrisome in terms of his being out of the cockpit that long and only the pilot and a stew in the cockpit. Now why there have to be two people in the cockpit and one is a stewardess is a bit of a mystery to me. If the pilot dropped dead, is the stewardess trained to take over? A co-pilot chatting in the galley in an emergency is not a lot of help.
