I do know it isn't the same and really I was being sarcastic and never said it was equivalent!
However, taking your reasoning one could relate it to a service pretty easily. A hairstylist is on the clock for 8 hours, they don't have any customers scheduled who can pay for the haircut in the next 10 minutes, but a college kid comes in with no money for a haircut, should the stylist provide them the cut anyway?
That is a better analogy than your first one.
The hairsalon "hasn't lost a buyer since the student couldn't have afforded it anyway!" (as quoted from your post)
Is that more equivalent for ya?
