Okay, so here is this senator from North Carolina named Thom Tillis. He thinks restaurants should not be forced to have their employees wash their hands. Instead, he thinks the market will handle it, and that signs indicating whether or not the restaurants have their employees wash their hands should be posted. Okay, here's the thing: this is assuming that everyone is rational. There is the occasional maladroit who forgets to wash his hands, and contaminates the glove box with bacteria (he was using the toilet). That's a minor case; a major case would be that a restaurant doesn't force its employees to wash their hands and get away with it; after all, not all food poisoning cases are immediate. And it would take quite a while before the markets react to decrease the demand for its services. *Never mind that forcing restaurants to post a sign telling whether or not it has its employees wash their hands after using the restroom would be considered regulation. Nice try.
