Most who enter look at the wet dog tied up to something out of my view. It looks sad. I don't know if all wet dogs look inharently sad, or if this dog is truely sad. Hair matted to his body and legs, making him look much smaller than he would when dry.

No. He must be a sad dog. A dog that an angry teenage boy would want to kick as he walks by. The kid who probably plays high school football, wears button down shirts untucked with a baseball hat. A kid who got pissed when he didn't get a Mustang when he turned 16, but will probably get one when he graduates.
