Not sure what you are getting at here. I agree the delivery drivers are in the grocery store. They probably spend half their workday there and have to travel throughout the store many many times, each time navigating a different cohort of shoppers, and then come in contact with deliveree surfaces (doorbell, etc.) as well. The delivery driver has a dangerous job and is highly likely to get covid. When s/he does, so do all the deliverees.
