"Sure is some snack," Roy marveled. "You must've hocked your fur coat."
"Gus chipped in," Memo said absently.
He was immediately annoyed. "Is that ape coming up here?"
She looked hurt. "Don't call him dirty names. He is a fine, generous guy." (8.108-11)
Roy's poverty leads to some ugly envy when he sees what others are able to spend. He refers to Memo "hocking" her fur coat, which means taking it to a pawn shop and using it as collateral on a loan. The fact that she didn't make any sacrifice, but rather that Gus was the one who paid the bill, really bugs Roy. He could never afford such a feast.
