That reddit post is the only source. It's in a mall. Even if those are real pieces of paper and a real picture of one of them, it would be elementary for some chode looking for internet points and lulz to stage it.

I'm curious to know the logic behind putting up three of these signs on the front of the same closed store, when you didn't have enough pieces of tape to hang them all and had to use a piece of tape from something else.
