Both. The trailer trash (of all races) leaves plenty of trash. I ran in to a WalMart last week to buy a roll of film. It was a wonderful reminder why I regularly don't shop there.
I could only shake my head and laugh......
The cleanliness and general shininess of Wal-Mart varies quite a bit by location. In my area, they're virtually spotless; they just remodeled one of the SuperCenters, greatly expanded the electronics department. Plasma TVs, etc. OTOH, I visited one in the Delta several months ago and couldn't believe the difference. Dirty. Dusty. Generally trashy.
