There was a story once where an airline employee named Gay was dead-heading on an internal company flight. But last minute bookings meant that the airline urgently needed the seat for a revenue passenger and were going to transfer Mr Gay to a later flight. So the FA came down the cabin asking likely looking dead-headers asking "Gay? Are you Gay?" After a few "No ma'ams", they found the right passenger. "Are you Gay?" "Yes, ma'am" "Well, I'm afraid you'll have to leave this flight".
Now some precious old queen had witnessed all this, got out of his seat, flounced up to the FA and hissed "Well, dearie, I 'm gay too and you're not going to throw me off just for that!"
