My Dad told me how back in the 1970s he worked at a government-funded research lab. One time they called up a laboratory glassware supplier and said "We'd like to order $10,000 worth of glassware". The supplier asked "Sure, what specifically would you like to order?" The lab replied "We don't care, whatever you have in stock, so long as it costs us $10,000 and we pay you today – if we don't spend the money today we lose it forever".
