I can't seem to find the post, and my memory is not so sharp (after a 5+ hr flight) so I will just post the question.

My wife turned her ankle while we were in LAS. No major injury, just needs to wear an ankle brace for a few days and take her time walking. I figured this was exactly what pre-boarding was meant for, someone who needed a little extra time walking down the jetway and should not be standing any longer than necessary.

Went up to the podium at the gate, and asked the GA for a blue sleeve for my wife. She looked at her and asked why. I pointed to the ankle brace and said "her ankle".

Am I correct in recalling that in a previous post, it was discussed why they could not question the request?
