How it works:
- You pass the cash to a waiter/vendor, he disappears and reappears again telling you that the note is counterfeit (he has swapped it) and asks you to pay again.
- If you do, you would have paid double effectively!
Places to beware:
What to do:
- For larger bills, you can mark them with a pencil (though not always practical) or remember the serial number of the bill before handing over.
- Also, keep the bill in your line of sight after handing it over.
