you say it's a $60 loss cuz you sold $60 of product
and it's a $40 loss cuz u gave change back on the purchase
-60-40-100 = -200
where -100 is for stealing the money in the first place
i guess he never paid you +$100 for the $60 product and $40 of change then?
then how the fukk are you giving him $40 and $60 worth of product? is it for free?
he never paid $100 to you?
or is does -100 + 100 - 40 - 60 equal to -200 in your retarded math?
but you didn't sell it.

But they're the educated ones
