Of course, they’re real people!
Man, Willy Wonka & the Chocolate Factory was not a kid-friendly movie. It taught us all sorts of warped lessons, like people’s own stupidity will be the cause of their death, the rich are crazy in ways the common person can’t even begin to fathom, and that Oompa Loompas were interchangeable and had not worth caring about.
Which is what makes us question why this guy showed up at the airport in full Oompa Loompa garb. It appears that he’s picking up someone named Chocolate Johnny. We hope that’s a reference to the movie. Forgive our uncultured ways, but we haven’t seen it.
