Masks aren't the most effective form of safety though they help. Staying home is more effective and I can tell you since I'm still working in a restaurant, almost no one in vegas is frickin staying home. We were packed out the ass last weekend for christmas. No one cares. They'd rather have their fun than practice being safe.
Now, I get it, I need those customers to come in to even have my job still, but if even half of them decided to stay home, we'd be okay. But nah, everyone is selfish.
