Depends on the state.  In NV the governor is using OSHA to go after the businesses that don't force their employees and customers to wear the mask.  Last week face mask wearing/not wearing was about 40/60.   Since the gov has gone after business licenses, it's almost 100% wearing.  Our governor firmly believes in that meme "It wears the mask or it gets the Phase I again."  He even has a snitch line.
