at check-in the AC agent gave one of our party a second print out of my boarding pass instead of their own, which we did not realize until we were boarding (zone 2). When the issue was identified, I waited behind with them (after I had scanned my boarding pass) to get it sorted out (I also had all the boarding passes on my AC app so was going to get that out). One of the gate agents decided to go on a power trip and force me to board, or else be deplaned and forced to wait until everyone else had boarded (I had no interactions with this gate agent prior, she just came out of nowhere guns blazing). Of course she was yelling for reasons unknown. I wasn’t going to board (or fly) without this individual so I waited just before the jet bridge. This gate agent literally follows me to tell me to board, instead of 1) boarding other passengers or 2) dealing with the situation with the last member of my party. She then starts harassing my party member, forcing them to measure their (clearly undersized) carry-on while everyone else is able to board without doing the same. Eventually this person I was travelling with found a copy of the boarding pass by email, and the other, not insane, gate agent was quick to usher them ahead.

I’ve never had an experience like that, completely unacceptable behaviour from the gate agent. I’ve reported it to AC and hope they take meaningful action.
