Check out the image in the upper left hand corner.  It depicts a person carrying their parking ticket to the Express Pay Station.  But holy crap!  The ticket is the size of a large briefcase!  
I realize if the image was drawn to scale, the ticket would be minuscule.  But that doesn't justify drawing a ticket the size of a large toddler.  The image is presumably included for non-English speakers, but does anyone think a non-English speaker is going to understand what the hell that stick figure is carrying?  I can only guess the stick figure is carrying a ticket because I can read the words on the sign.  
I've seen cave paintings that communicate better than this sign.
