Use her hair as a pissrag and move on
From Create Your Own Story
"Don't thank me you fat whore."
You comment as you grab a chunk of her hair rather forcibly and use it to wipe off your cock.
"The next time you are in my way I am shoving the toilet bowl cleaner up your ass."
She whimpers sadly at your comments and you can tell that she's on the verge of tears but that doesn't bother you as you walk out into the hallway your stomach growling loudly in hunger.
