I support enforcing hand-washing 200%. I've always washed before playing on location, mostly to get any food grease off before touching games, and in the last year have taking to washing before leaving, so that if i'm touching my face on the drive home, I'm clean.
Hand-washing has been the most effective germ killer even before this pandemic got bad, and if any "new normal" changes stick after this, I desperately hope it's increased hand-washing. The thought of people suggesting we should cut back on handshakes or hugs, yet there will still be people leaving the bathroom without washing their hands, is absolutely infuriating.
