The Missing Dollar...

Three friends check into a hotel room that costs $30. They each contribute $10, paying a total of $30. Later, the hotel manager realizes there's a special discount and decides to return $5 to the friends. He gives $1 back to each friend and keeps $2 for himself.

Now, each friend has paid $9 (totaling $27) and the manager has $2. If you add $27 (paid by the friends) and $2 (kept by the manager), it adds up to $29. So, where is the missing dollar?

There is no missing dollar.
