Where is the other pound...??

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 POUND?

Robbie, did you have a break away from numbers or just the internet
