₦1000 actually........Tapout got it 1st

The man has only lost #1000.

He took #1000 from John and gave him back, thats just #1000 from his own account.

i been dey some form of algebra

he lost just #1000
.......The woman gave him a counterfeit #1000, he gave it to John, who gave him #1000 in #200 notes....He then gave the woman #800 and kept #200 (the initial cost of what she bought)....now John comes back with the counterfeit #1000 and he(the shop keeper) gave him #1000 from his (the shop kepper) account. He then destroys the counterfeit #1000 note........y some people come dey talk #2000

Very funny you guys should say he lost #2000.
The shopkeeper only lost #1000 and that's the counterfeit money. The #1000 he gave John is the only money he lost.
Look at it this way...
*He got a #1000(change) from John which he thought is an equivalent to his fake note. He hasn't lost anything yet.
*He gave the customer a good worth #200 and #800 change totalling #1000. He hasn't lost anything yet.
* John comes back for a refund of #1000. He is now in possession of a fake #1000 note which he destroyed, therefore he lost a #1000.

It is like him collecting #1000 from John, gave it to the customer and paying John latter.

But come to think of it, if the guy can also spend the fake note he wouldn't have lost a dime.

For those who will argue that he gave out #200 worth of goods, don't forget he has #200 change with him from the #1000 change John initially gave him.

*What he actually lost is #200 worth of goods + #800 that he gave the customer =#1000.
QED

The lady going with the N800 change and N200 worth of goods gained N1000 - initially John's, but when John returned the counterfeit to the shopkeeper - the loser becomes the shopkeeper.
