People who just through their trash on the ground even when a trash can is present. I took my wife's car to the car wash yesterday and the area they provide to shame the car afterwards has a trash can, but the ground is covered with tissues, Q-Tips and paper food wrappers laying all over the ground. Not usually like this but yesterday someone decided to dump all of the trash from the inside of their car all over the ground. They have the option of a trash can in plain sight or even vacuum cleaners that could be used. I guess the two steps from their car to the trash can was just asking too much off them.
