I never answer these things, but this time I will. I have a very large number of lookalikes all over the planet. I know this because wherever I go people ask if I'm from [place] or went to [school] or if I ever engaged in [public spectacle].
I have a very familiar face.
I also almost always look sufficiently like an employee—despite not wearing a colorful vest or a particular sort of polo shirt—that other customers often ask me if I'm a worker when I'm in a store of any size.
