It's true that there is no easy way to verify compliance with the regulation about washing hands so you might consider it pointless. But what are the alternatives. Tillis' idea about opting out and posting a sign is stupid. Who would actually do that?
I don't consider hand-washing pointless and neither does Tillis. He wasn't making a serious suggestion to do that, just using an intentionally ridiculous illustration to try and make a point. I suggested some things, like antimicrobial doorknobs and fixtures, and also pointed out the CDC study that recommended a tactical reduction in hand-washing to increase hand-washing compliance.
Having a regulation about washing hands at least makes employees think about it. They have to make a deliberate decision to ignore the sign, ignore the regulation. It might make some people wash their hands that otherwise wouldn't. How much good does it end up doing? :idunno:
The sign is for customers, not employees. It makes customers feel like the employees are practice hand-washing, which gives them a false sense of security. The signs should say, "Wash your hands BEFORE and AFTER using the restroom." The regulations should require that, too, don't you think?
But on the other hand, let's say the government removes that regulation. Most companies will probably keep the policy at least for PR purposes. There is still no way of knowing if anyone follows it. And employees would still have to make a deliberate decision to violate the company policy. Perhaps that would accomplish the same thing the gov't regulation does.
But since we have it, what's the point in removing it?
Nobody wants to remove signs or abrogate the regulations. He was making a point about opting out of certain regulations as long as the business gives disclosure. It would help if we knew what the "certain regulations" were that he was discussing when someone trying to make a point asked him about the need to have mandatory hand-washing regulations in restaurants.
