Don't have a face mask? Just use a diaper instead! OK, it's definitely not ideal, but this guy in California didn't have anything else to use when he was trying to pick up some beer on his way home. Since face masks are mandatory where he lives right now, he had to do his duty to cover his face before he went into the store. Sure it was unconventional, but it actually wasn't a bad idea because he was able to get the beer!
