Years ago I looked for all stainless coffee maker and even the most expensive ones had plastic parts. The drip mechanism for all of them had plastic parts. I don't know if they have changed or not.
what, they don't have their company-provided mug with the company logo on it? Though to be fair at work, most employee have been given a mug, there's a stack of freely usable mugs next to the coffee machine and there's a dishwasher there too so you don't have to wash them by hand, but there are still people using the paper cups.
