While I was working as a temporary barista in Starbucks before I went to UK, someone told me this. It’s very interesting…
3 friends went to a hotel and rented a room. At the check-in counter, the receptionist said the room rate was $30 for a night. The 3 friends agreed and they each paid $10 for the room.
3 friends X $10 each = $30 for the room
After leaving the counter, the receptionist realised she made a mistake, and that the room rate was only $25 for that night. Therefore, she asked the bellboy to return the $5 which has been over-paid to the 3 friends.
$30 originally paid – $25 actual rate = $5 refund
As the bellboy walked to the room to return the $5, greed sets upon him and he decided to ‘steal’ $2 from the refund of $5 and thus, only $3 were refunded to the 3 friends.
$5 total refund – $2 ‘taken’ by bellboy = $3 refunded to the 3 friends

Back to the story…Those 3 friends happily accepted the $3 and they divided the $3 among themselves. Naturally, each of them got $1 each. Since each of them originally paid $10 for the room, their individual cost is now $9.
$10 paid per person – $1 refunded per person = $9 paid per person
Now that the 3 friends have been refunded $1 each, they each only paid $9 for the room (as shown above). This would mean, the total amount paid by them is $27.
3 friends X $9 each = $27 paid
Since the 3 friends now effectively only paid $27 in total, and the bellboy has ‘stolen’ $2, this would only amount to a total of $29.
$27 paid + $2 ‘stolen’ by bellboy = $29
Now… Ladies and genitalman… the room rate was originally $30 and those 3 friends originally paid $30 (i.e. $10 each). But…$27 paid + $2 ‘stolen’ by bellboy = only $29!
Where is the missing $1?
This is not a trick question.
