The old guy is called Epsom because he once made the mistake of telling his friends he bathes in epsom salt. For some reason, they found this hilarious. He's been Epsom ever since.
He is eating at the counter with his nephew, Will. Will looks far too young to be Epsom's nephew. They're related through some convulted family mess that I don't care enough about to understand.
Epsom has a Reuben, the boy a grilled cheese.
Though neither of them has said a word the whole time I've been there, Epsom turns to Will and says, "Don't be redundant."
