So Disgusting How Dirty People Leave the Bathroom after Using them...

Are we grown women?  Some people leave the toilet so dirty after using them.  Next person who walks in get thoroughly grossed out.  You see drops of urine or worse all over the toilet seat.  Why can't they use a piece of toilet paper to cover the part they sit on or use the seat cover provided?  Do they have to pee with their ass up in the air??  Is this really necessary.  It is such a bad etiquette and selfish.  What is your opinion on this?  Please leave a comment.
