This is absolutely common in the US in pretty much any large city, I can't imagine someone having never seen this before in the US unless they never lived or went to an area that was diverse. And its not just Chinese, many places will have Korean names, Japanese names, and of course on the other end Spanish names accompanied by english but most are more used to this.
A reasonable interpretation of "you see that everywhere" is "most cities have a mall or neighborhood that would result in a similar set of pictures.
It's incredible how many "hackers" in this thread don't understand how quantifiers work in contexts other than code. How the hell does this industry translate business needs into code without this rudimentary skill?
It’s quite likely that the only people around here who can read the Chinese menus work there or are related to those who work there.
Personally I think it's great; it means that you get some exposure to other languages even if you never leave your corner of the woods.
