I often get funny looks when I'm joining the priority queue or sitting in J. Being a swimming instructor woman in her 20's will do that I suppose, but flying a lot domestically, having a couple of big overseas trips, family pooling and being smart & loyal has gotten me WP with Virgin. My husband and I got a full on up and down look (and a sneaky check of our bp's) by a well dressed man boarding first class in Detroit. He's lucky he didn't say anything; I could almost hear the "this is for first class only" line on the tip of his tongue.
As for nasty FF's, I had a doozy of a woman on a flight from FLL to JFK in September. We were seated in first on Delta and she was a typical sounding abrupt and obnoxious New Yorker. I overheard her saying she had something like a million miles with Delta, so obviously a regular and she sure made it known. It started off by her discussing how she didn't want any refugees to come to America. Then it proceeded to her whining about her meal and drinks. Then I really started shaking my head when she was losing her s**t at the fact that the economy passengers were using the first class toilet *shock horror* She asked the flight attendant why they were coming up the front and told him to shut the curtain (let me add that not once during the flight did she move out of her window seat, so not sure why she was so perturbed). This went on for a while. He later tried explaining that being a 717, the only galley is in the front of the plane and that FAA regulations state that they be allowed to use the first class toilet whilst there is a cart in the aisle. Well, she wasn't having any of that and said she was going to be complaining to Delta and repeatedly kept asking "who designed this plane?!" to which he cooly replied "Boeing". The real kicker was when we were walking up the air bridge after getting off the plane and we all stopped to let a fragile woman get placed in a wheelchair. Her response - "Walk!! What's going on? Why aren't we moving? I don't get it!" at the top of her lungs in the most self absorbed obnoxious way possible. Vile woman.
