Rex Manning was like

I watched the film agin last night on Amazon ,
I'd never noticed that blue cheese comment before ...
Didnt understand it , not sure i want to ....

Pretty certain that was intentionally done to chase her away. There is an outtake that shows him giving up and walking away from a business that didn't even allow him to play on his last three records. I think the character was supposed to be a better person than what was left in the film - or, has a salad dressing fetish.
