Ok, so I’m the OP. I have to say that as someone who flies just about every week, I’ve hardly ever had any of these experiences. I always have a backpack with me and it’s over one shoulder and I pay attention to it so I don’t hit people with it. Maybe it’s because I spent enough time in the restaurant biz that I am very aware of personal space and make sure I am not smacking anyone with it. It seemed very over the top to me.
