Turns out that you don’t have to go all the way to a Haidilao restaurant to watch some public porn, just walk around outside long enough and you’re sure to see some.

On the night of January 2nd, a large advertising screen in the Jiangsu city of Liyang began showing pornographic websites and playing lewd videos. This went on a for a whopping hour and a half.

The display was reportedly caused by a horny worker who believed that the screen had been turned off for the night and so decided to make use of the computer that it was hooked up to. A number of passersby snapped photos and took videos of the unusual screening until finally a coworker was alerted and called in to the office.

While a mischievous customer is believed to be behind Haidilao’s recent in-restaurant porn viewing, most of the time this kind of thing happens because of workers who were thinking more with their little head than their big one.
