Plastic bag use went up in California because of covid. Some moron said reusable bags spread covid germs. So stores banned reusable bags for many years. It's just back to normal where reusable bags are acceptable to bring in by the customer.
If you take plastic bags and stuff them into a pillow case and then seal the pillow case with a zipper, you can make plastic bag pillows. The more bags inside, the stiffer the cushioning. Reuse is important too.
