To be fair, it is literally true that I am at least partially responsible, even if only by one part in a million. If there were a million people like me, and we each individually and separately decided to refuse to use the kiosk and demanded to be served by a human cashier and left the store if one was not immediately available, the owners would have no choice but to keep the humans. I just happen to like the kiosks because I am not a luddite.
