First of all, if you buy out all the soap and sanitiser so there's no left for anyone else, you're not really that safe. Because everyone else is walking around spreading germs anyway.
But also, don't panic buy. Shops won't close instantly. Once the government tells everyone the world is on lockdown, then panic buy, but for now just stop being an idiot.
Educate yourself, wash your hands. Tired of seeing people buying PPE for builders/decorators and using it as a sanitary mask (not medically approved). Or wearing masks that don't cover their nose, just mouth. Also wash your hands after using the toilet anyway.
What's really scary is that if there was a real threat to humanity we'd kill each other with our stupidity and selfish greed quicker than the actual problem would.
