^^ my absolute favourite. Rarely fails to get a comment about it being a priority or c class line or something from someone looking down their nose at me and my backpack and book bag. Usually get a supportive comment from the agent as well which is always awesome. like one that told first guy in economy line who tried to argue to get ahead of me that "he pays for most of your ticket, you should thank him". I was a bit embarrassed but it was nice to hear.

This debate is much like the tourist/traveller distinction. Mist of the people who care much about it are the ones trying to make themselves look better than others.
