I have seen “smears” on the seat at a shopping mall and public maintained bathroom as well as a service station. I have even seen shoe marks on the toilet seats.... No idea WHY someone would squat over a toilet seat....
I have seen shoe marks, I agree. I avoid any sort of service station rest rooms, in fact, I think of that *smell* as the smell of a Texaco bathroom.
Perhaps it depends on what part of the country you’re in. It’s sad that people refuse to clean up after themselves.
It's a cultural thing; what they were raised with.
They just can't figure out why is is so blastedly high off the floor!
