I showed up for 743 (operated by a 333) at YYZ F61, right before they called zone 3.
The GA looked at the one person in the 1/2 line and asked "zone 2?" as I got in line behind her. She said "no" and didn't move. So I said "zone 1" and the GA held back the masses for me to step around the incorrectly positioned person, and I boarded.
Quite pleasant. Except for that one person. She knew she was not 1/2 but she felt the need to stand in that line
