Some fucking guy used my office restroom and didn't flush the toilet 😡

Disgusting! And I know it was a man because the toilet seat was up and it's just me and my two assistants, who are also women, who work in this office. What a pig, whoever it was! My guess it was one of the overnight maintenance guys since the men in my department have no reason to use our restroom. They're lucky I don't know who it was... I'd love nothing more to drag his ass in there make him flush the toilet like a little kid, since he can't remember to flush it like one!
