This doesn't really add up though because in reality the butcher would just use invoice finance to get the money ahead of time at a way lower cost than a 50% discount he's offering, which would probably include some insurance if the restaurant went under. It doesn't make sense. Invoice finance might cost 5-15% of the invoice. Why wouldn't you do that rather than giving customers 50% off? I can get a small discount but half price doesn't seem realistic.
