As Simple As This Riddle Seems, Some People Still ‘CAN’T’ Solve It!

This looks easy but it is not because everyone will arrive at a different answer…
A lady bought goods worth ₦200 and paid the shopkeeper with a ₦1000 Note.
The Shopkeeper had no change on him so he went to another Shopkeeper John his neighbour and collected ₦1000 change in
₦200 denominations, with which he settled the lady and she left.
A little while later, John came back angrily after he discovered the ₦1000 note he was given by the shopkeeper was fake, and demanded a replacement.
To avoid trouble, the shopkeeper had to give John another ₦1000 and destroyed the counterfeit which had no real value.
So Question for the geniuses…
How much has the Shopkeeper lost in total?
