Later the attendant recalls the room only costing 25.00, so he tell the bell boy take this 5.00 up to the guys and split it three ways. On the way up the bell boy decides it to hard to split the five dollars three ways so he keeps 2.00 and them each 1.00. That makes the men paying 9.00 ea. which equals 27.00 plus the 2.00 the bell boy kept equals 29.00. Where'd the other dollar go?
