What I don't get is that their parent/grandparent/guardian/etc, who is an adult should know better. Yet, 95% of the time they don't say a single thing to their kid(s).... and/or will also walk directly through where you are to get where they want to go. They seemingly don't get 'oh, I guess I could walk around the guy on the bike to get to where I want to go'... nope... right through my line (and it's never really that much space)... time and time again. And since they've stood there watching their kid for 20 minutes, they should know where the f*ck I'm going to be when they decide to finally move.
