In the supermarket
In most stores, but most certainly in the supermarket, the store itself decides how many people can be inside at the same time. Almost everywhere it is mandatory to use a shopping cart, or at least a shopping basket. This, however, can vary depending on the location. It would be good if you do not go inside with more than one person at a time. Preferably also do not take your children with you either, unless it is absolutely necessary. In most stores rules are clearly communicated at the entrance. This rule also applies to all Qurios Parks, at the reception, and in the mini-shop.
