Back in the day I did consulting work on a personal level for an ultra-wealthy person. He was into making electronic music as a passion. This was in the days of 486/pentium, so the tools available to do this were relatively expensive. He'd create something and slip a couple of hundred to a club DJ to play it when he went out.
Anyway, he would use a floppy and throw it away. I realized he did this to save time. No need to format the disk and reuse, he would just pull another one out. He was buying time.
It infuriated a relative of mine when I told the story due to waste, but I explained to her those minutes he would spend formatting the disks wasn't spent. He came out ahead.
