Here's why this is a bad idea from a non-biased observer, my wife. Today we were flying back from a vacation and the pilot was helping out at the counter. Then walked us to the plane. When he got in the cockpit my wife elbowed me and said, "That was the guy taking the ticket, what's going on here, are you kidding me?" She was worried the entire flight b/c a pilot was doing something other than her perception of his duties and she wondered what else the airline might have cut back on as well. Did they have a ramper helping with maintenence? I'm all about helping out and I do, because we don't carry pax who have an expectation of what a pilot's duties are. We are all professionals and we need to act the role if we command the pay. Would you feel confident about your surgeon if he was scrubbing the crapper before your operation, didn't think so.
