Hotel -- riddle

[iago]

Three men checked into a hotel room for which they paid $30.  The next day, the manager glanced at the records and realized that the men had been overcharged.  She gave the bellhop $5 to return to the three men.  On the way to their room, the bellhop decided to keep $2 for himself, and give each of the three men $1.  The three men had now paied $9 each, or a total of $27.  This, plus the $2 the bellhop kept makes a total of $29.  What happened to the other dollar?

You don't know how to add! The men paid $27 - $2 to the bellhop and $25 for the rooms!

Good, though, I'll have to find some more of these sometime.
