I can't find the thread, but I believe I have already recounted a few years ago on either a LHR JFK or CDG JFK flight, my barely legal drinking age seatmate (the FAs asked her a second time for ID after her fourth drink within 1 hour after takeoff!) who had forgotten her underwear and was making everyone painfully aware of her barebottom situation by hiking her dress up to her waist when seated with her seatbelt fasten or when retriving things repeatedly from the overhead bin. After I mentioned it to the FAs, they said that they hand never seen anything like it and didn't know what to do. I asked to be moved, but there were no empty seats. One PAX joked, I guess you will just have to grin and bear it! I responded, I hope you don't mean like her!
