We used the paper bags to drain homemade French Fries. I don’t think they even had Scott Towels back then.
I love my blue grocery bags, they hold a lot more than plastic, can put 3 times as much in one as in the plastic bags and have heard a lot about bacteria...I can BS on the so called bacteria in the bags....
When I was in nursing school we read about a study done on the bacteria in public restrooms...the cleanest part with the least bacteria was the water in the toilet...lets all drink that water.....studies find what they want to find...and nurse's learn to wash their hands quite a bit differently than other folks....the more germ ladden thing in the public bathrooms are all the door handles.
Come out of the toilet touch the handles of the door, go to the sink and turn on the water with those same hands...wash hands and turn off the water faucet and get back on your hands all the bacteria you just washed off.
Wash your hands and use a piece of paper towel to turn off the water. Push the door to get out of the restroom with your butt and not your hands if possible.. the simplicity of proper hand washing keeps lots of germs off you...
