I had new rear tires put on the truck last week, and they had a tape barrier that you had to stand behind. I had to go back this am (faulty valve seal) and they had put up a row of off-road tires in front of the counter, making you stand back. Seemed to work well, wasn't really noticable, and doesn't hurt advertising.
I am guessing we will see more of that, people working around the whole thing, and gradualy deciding that more things are "essential." People will get tired of these shutdowns in areas with few infections, while cities like NY will become less and less desirable. Life will go on.
