I appreciate the extra measures that businesses are taking — and telling me that they are taking — to help keep me free from Covid-19. But, some of them are surprising not because of what the business is doing, but because, apparently, they were not doing them before. One airline sent me an email proudly announcing that they are now cleaning the tray tables and seats! What the heck were they doing before — waiting for some kid to spill his orange juice and then wiping up the tray table and seats with the OJ spillage?!
