1. Empty supermarkets
People not only stock up on toilet paper but also on pretty much all other products they can lay their hands on. With every country imposing different measures, it’s difficult to predict and keep track of what might be happening. That is one of the reasons you should not even try to predict anything.
Predictions are very often wrong, and the best thing to do is just listen to the WHO and measures imposed by the government of the country you live in. Try to keep your mind at ease and only get the necessary stuff. This way you’ll leave something for the people with vital jobs, like nurses who want something to eat when they come home from their jobs at night.
