Erwin and Levi were known for being widely respected...and being absolute polar opposites.

You were in the mess hall with Jean, Eren and Mikasa. Jean and Eren usually bickering, you and Mikasa talking normally. Then another recruit approached, and for some unknown reason, slammed a wooden platter on your head. "YOU DAMN TITAN SHIFTER... YOU'RE A SPY!" They yelled, and how four of you looked at the poor recruit. Oh, and what a coincidence how Levi and Erwin walked in on them.
