Rubin’s diet consists of vending-machine sandwiches, Pakistani takeout food, and espresso. I’ve never seen him eat anything else. We eat samosas in a narrow shop on Fourth that has a single plastic table wedged between the counter and the door to the can. Rubin eats his dozen samosas, six meat and six veggie, with total concentration, one after another, and doesn’t bother to wipe his chin. He’s devoted to the place. He loathes the Greek counterman; it’s mutual, a real relationship. If the counterman left, Rubin might not come back. The Greek glares at the crumbs on Rubin’s chin and jacket. Between samosas, he shoots daggers right back, his eyes narrowed behind the smudged lenses of his steel-rimmed glasses.
