You decide to leave the house and go on your walk. Even though you are by yourself, you are still carrying a mask with you just in case.
You're continuing on your walk when you pass a sign offering a limited edition food item at your favorite restuarant.
You are very hungry since you forgot to eat today so you deicde to go to the restuarant and get that food item.
You put on the mask you brought with you and are let inside.
