I think there is a tremendous opportunity for a new product to be developed and sold. Imagine for a moment using the basic hoola hoop as the base, but making it somewhat larger. Using the invisible dog fence technology with a neck collar which will simply zap the wearer/shopper if you're getting too close to the person nearby honoring the 6ft required space between the nearest human being. That is one way to ensure we're safe while shopping then the designers of the store aisles can figure out how wide to make the aisles for the best way for us all to maintain social distancing while shopping. Then the same store designers can adapt a new way of shopping for produce, meats and baked goods by simply not allowing any customers to touch any of those items, just take a number in those departments then wait for your number to be called, just like at the deli counters. Finally, set up a row of one person self checkout stations with a safe distance for the next person waiting to check out. Oh yes, I was just thinking about some sort of automatic shopping cart collection and sterilization system (that can also be newly designed, see more good old American ingenuity), created and built then implemented, see, its all settled. Let the suggestions commence.
