When I shop at my local Trader Joe’s, you can choose between brown paper and plastic shopping bags. I always choose plastic. If the cashier looks like a hippie Lefty, and they give me a look when I ask for plastic, I just say “God, guns, guts, and plastic make America great”.
At the Fort Campbell Commissary they also ask if I want Paper or plastic. I don’t mind paper but they are hard to carry. Most the times I have my own bags, but If I forget to bring them I just say plastic, though I hate plastic bags
