@female_flyer I don't mind being asked if I belong. But there is a way to ask.

GA TA FA PA MA (I added more A's in there than there actually are) shouldn't assume I don't belong or anyone else doesn't belong because of what I or they look like or something. Don't imediately tell me "The Regular People line" is on the other side.

If you are worried that I am blind and can't read the sign that says "First class and Medallion" then make a general annoucement and say its a first class medallion line only. Don't make it obvious that you are just directing the message to one person either.

When I was young and worked in Retail and hell if you ever watch that hooker show on HBO with the bunny ranch. My old boss when I worked Retail and the Hookers from that show all say the ones that typically dress the nicest are the ones that typically can't afford, and the cheap ones tend to be the rich ones.
