Well that was lovely. Traversed the priority line in the transborder area at yyz. Got to the CATSA agent waving people through, he had his back completely to me. No acknowledgement that he saw me. After a minute I cleared my throat and said hello and got a snarky "I know you're there. You'll wait your turn.".
Funny, I thought qualifying for the priority line meant I didn't have to wait. He waved through about twenty more people just to drive the point home and finally let me through. What a Jack@ss.
