How Not to Walk on a Multiuser Path

Hey two guys walking one on either side of the yellow line with large shopping bags filling most of the rest of the path.  I dinged the bell and you didn't respond, you were lost, no doubt, in contented contemplation of the contents of your really large bags.  I had to say something to get your attention so lost in thought were you.  Next time, you might stop and think about the multi aspect of the multiuser path before you begin to amble contentedly while taking up 80% of the space.
