Human societies can be sneaky and deceptive. I’ve encountered incidents like that, but mostly in China. You pick the fruits, then just as you’re looking for your wallet, the seller swaps your bag for another one with all the rotten fruits. Luckily I checked.
And if you think that it only occurs in China and India, think again. Maids in Singapore are often bullied at markets. They may know how to choose fruits, vegetables or prawns, but some vendors would force them to take the rejects. Never send you maid out on such errands.
