Where is the other dollar?

This will Mess With Your Head

3 men go into a $motel. the man behind the desk said the room is $30, so
each man paid $10 and went to the room.

A while later the man behind the desk realized the room was only $25, so
He sent the bellboy to the 3 guys' room with $5.

On the way, the bellboy couldn't figure out how to split $5 evenly
Between 3 men, so he gave each man a $1 and kept the other $2 for
Himself.

This meant that the 3 men each paid $9 for the room, which is a total of
$27, add the $2 that the bellboy kept = $29.

Where is the other dollar?
