First, thanks to those for the welcome. And glad to hear the pushing and shoving is all around!
In response to whether I did see if they were questioning everyone, yes, I did. I fly the exact same route each week, and it is the same pushers, shovers and questioners. I do reply "I am in the right line, being a platinum. Are you asking everyone?" The person usually turns away a little embarrassed.
And I'm not naive to think it is due to me being female. It is due to me being a younger female. I see a lot of the same women on my flights. Just not anyone my age.
