If the Bellboy was really a future Congressman he would had kept the $5.00 and told the 3 guys that due do some unseen circumstance the room had increased to $60 per night and since they had already signed the contract it would cost them $200 to leave the hotel and get their money back.
Later that night the Bellboy would be caught in some scandal involving an underage maid after taking kickbacks from the phone company for putting defective phonebooks in the hotel rooms.
