A career in what?!

Relaxing on a sofa in The Yard at the Iron Horse, there's a conversation next to us that goes like this:
"I got that great new job, pending the background check which should not be a problem. Then the guy calls me to say there's a domestic dispute on my record. I tell him it's from an argument with an old girlfriend but the charges were dropped - it was no big deal."  The dude then goes on to say, "If they rescind the job offer I am going to kill that bitch." 

Too bad he can't hear himself. I wonder what kind of job it was.
