I’ve never heard of one. Maybe some ultra-rich, ultra-swanky restaurant could. But if the metal utensils are being disposed of, the energy and environmental impact of metal utensils is WAY higher than plastic one for one. It’s only because we re-use the metal ones that they’re better.
Obviously, you meant for re-use, but if you’re delivering to someone’s home, they already have utensils. if you’re not, then what are the odds that they return them? Seems inconveneient to the customer. Even if I put some kind of deposit into the transaction that could be recouped when the customer returned the metal utensils…I’m inconveniencing my customer. This is not a winning strategy.
