wasn't trump a winner of cheapest (fake) billionaire by trying to cash a $1 check, or something like that?
Though maybe the proverbs are not exactly opposites. One is about the quality of the outcome, the other is the speed in getting there. Perhaps that's the lesson.
It’s kinda rude to not cash a check, it leaves the money in limbo, see Seinfeld episode, and I’m sure Simpsons has done it.
