Overflowing toilet

Ah...Monday morning in fifth floor men's room.

Sombody conducted a pretty serious piece of business in the chamber this morning and there is now an overflowing toilet and an inch of water on the floor. (Good news: the drain does seem to be working.)

Did the offender try and use the plunger to prevent this overflow? Did he at least call the building manager and alert them to the problem?

I doubt it. While past performance is not an indication of future results, the users of fifth floor men's room are a notorious for their lack of responsibility.
