I'm not judging, but how exactly does that happen? Does the spoon fall into the trash while you're discarding something and you don't want to pick it up? Or do you throw out a container and miss that it had a spoon inside?
I can't say I've thrown away a spoon knowingly myself, but I have dropped cutlery in the bin once or twice. I haven't ever abandoned it but you can imagine people might if they don't value it. And based on the university, some people would happily lose a £30 pan rather than reach into the Stank Tank, so I can believe it.
The really nice stuff is only brought out at Christmas. As long as there are enough forks/spoons/etc for 8 people in the drawer for day to day use, then I don't care that much.
