This is a new one for me. YUL TB. Guy walking around (or trying to) wearing a jam-packed backpack that sticks out quite significantly. The food area is already relatively difficult to manoeuvre once a few people get in there. Now imagine trying to navigate around this guy. A miracle he didn't knock something over, lol.
Edit: I wonder if he's related to the person who banged me in the head with their backpack while boarding yesterday (I was already seated).
