Did you really pull out the physical card or are you just using it as a metaphor for mentioning your status?

I think its rather obnoxious to be flashing a card at GAs and TAs like your an undercover cop or something.

I think its clear that as a GM she was entitled to none of your benefits and therefore when she choose to to make the trip should have not expected any special treatment and planned accordingly.

Hopefully you're not building a reputation at your small airport that will give you problems in the future. I think you'd be better off working to make friends at your home airport so that the types of favors you've requested are granted vs. the response you received this time around.
