My family (parents etc) have mostly learned their lesson now after all the news coverage, but before that I used to resort to hiding my good non sticks whenever they were staying over. If my parents complained about the shitty old pans that were available, then I pulled out my very sticky nonstick ceramic pan that they had roughed up despite my protests. I'm never throwing that shitty ceramic pan away, it's way too effective as a rhetorical ploy now.

Friends I still mostly don't trust since I don't know their kitchen habits well enough, but they're less likely to try to help with cooking anyhow, only with dish washing and there it's easy to hide the wrong sponges.

If your chipped nonstick is teflon, then it's garbage now imo. I would never cook in it again, too risky imo.

And I now realize that I've become paranoid in my own kitchen.
