Derrick was a total ass in face of her sincere apology, though.

I agree with you 100% on this, and, honestly, it's made me dislike her. I mean, no matter how she does on Drag Race, she's going back to a regular gig that probably consistently pays more than most of the other queens in the competition make. She could easily afford to be more magnanimous given the circumstances, especially to Chi Chi, who is working two jobs outside of drag just to scrape by.
