Seen in the building where the moron from whom I bought a guitar lived. According to him, 'the Chinese' in his building simply couldn't get their heads around the fact that this button clearly stood for the 19th floor, and that 'unlike us' they would go up to the 20th floor and walk down the stairs if they wanted to get to his floor. This coming from the guy who superglued both nuts into a 1987 Fender acoustic guitar because it was a little humid in Guangzhou. Some people just don't deserve to have nice things.
