SamD wroteThe last one to try that with me got more than he bargained for. He counted out the Rp, all good, then asked for 20,000 or something to round it up and while I was fishing out the note he pocketed a couple of hundred from the pile. I counted it again and found the shortfall and went into mad Scotsman mode: I grabbed my dollars back, knocked over his flimsy counter and stomped it into matchsticks. I suppose it was a risky thing to do but I got out OK and nobody followed up. I had a look a week or so later and he was still there, sleeping at the back of his shop. I left him well alone this time.
Good job SamD....but risky knowing how mob rule exists...just yelling Maling! Maling! and a hundred men will emerge with sticks and knives.
But still good info for those unaware that slipping notes, after counting, while diverting attention, is a standard practice with these street currency bandits.
