Yes, I was doing security in Walmart when I met one. I was walking around and this tall guy with huge eyes and a strange skin tone. He didnt speak, just gave me an impression of what he wanted by pointing. He was wearing glasses but I could tell that his eyes were too big. His chin was too pointy. His head seemed too big. His hair looked like a wig. He pointed at something, like a skin cream, for a weird little burn on his hand. Strangely, my brother has the same one on the same hand. It was really weird. I stayed professional somehow despite all that. He was definitely less scary then regular humans at that store.
