Seafood shopkeep filmed ripping off customer

A Hong Kong shopkeeper has been nabbed ripping off a hapless customer using a sleight of hand manoeuvre impossible to detect without a security camera.

The woman is seen weighing a basket load of crab and after dumping the meat in a plastic bag, reaches down to a bag she had prepared earlier, subtly dropping the weighed seafood.

She then pulls the same stunt again, this time with fish.

The shameless stunt was caught on CCTV in a fish market in Kowloon and uploaded to YouTube yesterday, where it has been viewed almost 10,000 times.

It is unknown if the customer noticed he had been short-changed.
