When it comes to public restrooms, everyone is a little different. Some people have no problem sitting directly on the seat. Others feel a little uncomfortable with that direct contact, and prefer to use a seat cover, or even hover over the toilet. Whatever they choose to do is really their business, though.
A Reddit user got into blows with her conservative coworker, who decided to try and out her as transgender after using the bathroom after her one day. The only issue here is, the user isn't trans. After the user exposed her coworker's bathroom habits, other people in the room called her out for being "rude." So, she asked AITA if she was really in the wrong.
