There’s been some criticism of “hygiene theater” vs. what actually keeps people safe, but at the same time, at least some establishments are doing something, anything to move closer to safety rather than ignoring the elephant in the room. It’s true that if what you are doing doesn’t actually do anything, then you run the risk of appearing hypocritical. But it’s also true that if you don’t do anything, it shows you don’t care. At all. Action, even if it isn’t particularly effective, is still demonstrating to your customers that you take the situation seriously even if your methods aren’t entirely based in science. What would be better is if your actions are actually based in science. So quit the squabbling over hygiene theater and look at the data to find what works. And then do those things.
