I actually witnessed a similar thing today. A girl was going into an extensive history lecture to her boyfriend that later just got up and started walking away and then they got into a fight over it.
It comes from living in America and being around and previously working at places that may have a system where lining up would work well. Granted, the area I'm at has a large tourist population but that are mostly all Americans from out of state. It's anecdotal evidence. Maybe just my city or something.
Does the top part of the hat say "moron"?
Edit: apparently it's an "Л" not an "R"
