What single-use items (e.g. straws, coffee cups, vegetable bags, plastic bags) do you regularly use? What did you substitute or could be substituted instead?

What do you do if you find yourself in the situation of needing a bag for items but don't have a reusable one with you or aren't allowed to use the one you brought? Carry things out in your hands? In a cart? Accept a disposable one? If you find yourself in this position often, what system could you put in place to try to create a successful habit of not using plastic bags?
