I think I am going into the furniture business- I predict that from now on there will be rise in the sales of vastly oversized dining tables with glass tops - so that there’s enough room to seat each person beyond the arm’s reach of another and so that if anyone want to stretch they would be deterred because there would be no way to grope discretely.
For small homes there could be boothables- tables with hardware cloth beneath separating each seated person so as to prevent thigh-grabbing and leg-rubbing... and an optional clear tabletop barrier system like the dividers in a prison meet and greet room only with a small slot to slide dishes through as they are passed around.
Years ago, a physician customer of mine ordered a very large beveled glass table top. He had a topless table for 8 designed and special made.
He told me he wanted the table so he could see when someone was grabbing his wife’s thigh at dinner
