Toilet Training

So Senator Tillis believes that it is government overreach to require that restaurant workers wash their hands after using the toilet.

‘I don’t have any problem with Starbucks if they choose to opt out of this policy as long as they post a sign that says “We don’t require our employees to wash their hands after leaving the restroom,” Tillis said.

"..as long as they post a sign..."  Hmmm.  Would that be a legal requirement?  And if so, wouldn't that be another of those pesky regulations?  And supposing Starbucks wanted to opt out of that rule....
