Perhaps it is time to go back to the old fashioned stores of the 1800s that were set up like a bank.
You go in, up to a cashier and give him your list. He then sends a boy in back to fill your order and bring it to the cashier who then takes your money and gives you the merchandise.
I already do kind of that. I order online and have them bring it to my door. If I step foot in a grocery store now it’s for something simple that I ran out of like milk. I’ve been having my groceries and merchandise delivered for years.
