Me, laundry bag in hand, waiting for elevator to arrive to go down to the basement.
Other person, laundry bag in hand, arrives at elevator.

Elevator comes.

Elevator gets to basement.

We both exit and walk to laundry room.

Three machines free.

Me, reluctantly being polite: "Were you going to use one or two machines?"
Other person, looking at me I'm crazy: "Actually, I'm going to use all three."
Me: "I guess I'll come back later then."
