Just have the sample. Your refusal to not consume it isn't going to change them buying the plastic, because given the choice, people aren't going to stop sampling in the aggregate. And at that point you're just signaling to other people in a really silly way.
If you really care, talk to your local representatives or write to Trader Joes and Whole Foods. Anything else is posturing. Not taking a sample which costs them a few cents on the dollar is not taking action.
I'm not going to stop, personally. They can give it to me in paper wrapping instead if they want to make a difference, and in fact, with their cups, they already do. Let someone invest in paper sampling spoons.
