Answer:
Your answer is " They transfer microbes from one person's hands to another"
Step-by-step explanation:
You would not want to use these in hand-washing stations.
Let's say you have c-ovid-19, but sadly you do not have anyone to grocery shopping for you. So you go. You take all of the precautions to try not to give c-ovid-19 to anyone else as in mask, hand sanitizer, gloves, etc. You wash your hands at one of these stations before leaving so you go to dry your hands and you dry them on a public cloth towel. After that, you leave and you watch the c-ovid-19 cases rise in your area.
Hope this helps!
