P.S. DG: "Drafting" suggests a cooperative effort between two or more riders, each giving to the other. It also suggests a riding "intimacy" because you're each trusting your precious, fragile body to the other. Six inches off someone's wheel is a potentially vulnerable place to be. Always good to know the riding style of the person with whom you're riding nose to butt.

Man, I would never just drop in behind a stranger unless the rider gave off "I'm an expert" vibes.

Anyway, this guy sounds like a jerk. Most cyclists are lovely people....this person was one of the few brown apples out there.
