The Hotel Bill

Three people check into a hotel. They pay $30 to the manager and go to their room.

The manager finds out that the room rate is $25 and gives $5 to the bellboy to return. On the way to the room the bellboy reasons that $5 would be difficult to share among three people so he pockets $2 and gives $1 to each person. Now each person paid $10 and got back $1.

So they paid $9 each, totalling $27. The bellboy has $2, totalling $29.

Where is the remaining dollar?
