One-man Conference Room 

A very small room with a locking door that usually has large gaps in it and a single porcelin seat with water inside. The walls normally are suspended above the floor which also has a large gap to the ceiling. A roll of soft thin paper is almost always supplied in the room. Very often two or more conference rooms of this type are contained in a row next to each other in a larger room that usually has ceramic or tile floors. Rooms of this type are sometimes called a bathroom, restroom, water closet, among other names.

John: I have to take a meeting in the one-man conference room - I do not want to be disturbed.

Joe: Is it a stand-up meeting?

John: No it is a sit-down meeting.

Later...

Joe: How did your meeting go?

John: Negotiations were tough but it all worked out in the end. Of course no job is ever finshed until the paper work is done.

"Hey Woodward, you wanna come out to the club and pick up chicks with us tonight?"
"No man, I think I'm gonna drink a protein shake and have a one man party."
