The problem is what would they switch to? In Japan, they have disposable bamboo forks and spoons, at least I hope it’s bamboo and not wood.
So the answer is just bring your own fork and rinse it off when you're done.
Is it plastic in your parts? Plastic spoons always feel way too flimsy to me.
I mean sure, but this was an international long haul flight. I can actually imagine a 100 people trying to wash their silverware in airport lavatories on a 767 after dinner service.
Note: none of these were bamboo, they were all some type of lighter tree wood
Edit: if you’re not sure on the taste we’re talking about, chew on a wooden toothpick until it goes a bit soggy: same flavour.
