Interaction on a Subway Platform

(A Metro employee in a Metro hat is reading the Metro newspaper he was just handing out to subway riders)

Me (shit-eating grin): Eatin' your own dog food over there, eh?
(beat)

Metro Employee: Dog Food? What the fuck you talkin' 'bout boy? You think because i don't live in your fancy-ass neighborhood I eat dog food?

Me: It's... no... it's just an expression- you're reading the newspaper that you...

Metro Employee (walking away in disgust): Unbelievable! We got a black president and this mothafucka thinks I eat dog food! Probably reads all the white Atlantic Bloggers, even that Megan McArdle, but not Ta-Nehisi Coates. Nothin' changes...
