People who use private restrooms are bad people. Not quite open carry bad, but leave the seat up and not flush the toilet bad. So, pretty bad. If everyone used public restrooms instead of private restrooms, the quality of pubic restrooms would improve dramatically. Because, well, we all know that everyone using something automatically makes it better.
Disclaimer: I personally have no problem with OC. But this is a gun forum and I had to think of something some folks here might identify as "bad".
