Why are people panic buying toilet paper?

parcher (UK)

Back in the UK shoppers have emptied shelves of toilet paper across every supermarket in the country in panic over the virus. Pasta has also been cleared, preventing shoppers like me from purchasing anything. Why are people so selfish in times like these? We are all in this together, yet some think they have the right to stockpile certain goods preventing others from buying. During the wars the UK came together to help each other, but sadly today’s generations only think about themselves.
