(Michigan) We shop at two stores every payday weekend: Meijer, for just about everything, and Horrocks, for good deli meats and other special treats.
Meijer has plastic bags all over the place, but each checkstand has a stash of paper bags. I've seen them used for glass bottles and some frozen foods, and I imagine if you wanted everything in paper you could get it. Some people bring cloth bags. I have never seen or heard debates break out over the morality of one bag type over another.
Horrocks has cloth bags for sale. At checkout, paper and plastic are available, and the question gets asked. Never had a checkstand operator get huffy over my choice.
