My friend once told me that back in the 90s, restaurants and KTVs would place covers over the plates of their customers’ cars. The reason being that most of their clientele were government officials who, on their modest salaries, shouldn’t be able to afford a dinner or night out at such an expensive place. It was a response to local citizens taking pictures of the plates and recording the times that cars were there (sometimes for 3 hour lunches), and then lodging complaints. Those days were past, my friend said, but since returning I’ve seen a couple of restaurants and KTV places that cover the plates with a sticker that bears their establishment’s name.
