Watch: Viral jewelry thief prank has employees leaping over counters

Watch these poor jewelry shop clerks come close to a heart attack as they leap over counters chasing down customers who are running off with jewelry – except they aren't.
A viral prank in China, jewelry store 'customers' try on expensive merch, then sprint towards the exit door. As the store employee chases after them, the prankster then casually stops in front of a display near the front door, as if that had always been their intention. Although not so nice, it's hard not to chuckle at how well the frantic employee transitions into an about face and casually walks away.
How did this prank start? According to Oddity Central:

The jewelry-stealing prank craze is believed to have been inspired by an Indonesian influencer’s shoplifting prank, which went viral in Asia last month. Harvinth Skin posted a video of himself trying out a pair of expensive sneakers at a sporting goods store and then pretending to run out wearing them, only to then sprint back, making it look like he was just trying them out. The shop assistant can be seen running after Skin, and then breathing a sigh of relief after realizing he never meant to make a run for it. Chinese pranksters just upped the stakes by essentially pulling off the same prank at jewelry stores.
