5 year old Chinese kid running loader.

The way he is running it, he has been operating it for awhile.
It’s not unusual at all to see kids of this age working a cash register or handling customers in China. Blew me away the first time a little 8 yo girl scanned my item, took my money, and handed me my change and receipt in a store. Her mom, presumably, was somewhere nearby.
