Sweaty Chef
A man went into the "Sweaty Chef" Kebab shop and ate a meal costing 105 Madadian Wonks (local currency Madadian Wonk=MW), giving the owner, Mr Juan, a 500 MW note. He kept the change, came back a few minutes later and ordered some kebabs for his girlfriend. He gave the cashier a 100MW note and received 20MW in change.
The following day the bank told Mr Juan that both the 500MW and the 100MW notes were counterfeit.
How much money did the"Sweaty Chef" lose? Ignore the profit of the takeaway.

Answer
600 Madadian WonksSince the man's entire payment for each visit was counterfeit, everything he took - food and change - constituted a loss to the "Sweaty Chef".
On the man's first visit, the restaurant lost the 105MW meal that the man ate and the 395MW that the cashier gave the man in change. Thus, 500MW.
On the man's second visit, the restaurant lost the 80MW meal that the man's girlfriend took, and the 20MW that the cashier gave the man in change. Thus, 100MW.
In all, the "Sweaty Chef" lost 600MW in notes and food (or 415MW in just notes, but they should also count the value of the food lost).
