The long line to the supermarket

I really cannot come to terms why there should be long lines to the stores and pharmacies. During the lockdown the lines were terrible that it will take more than an hour before you can enter the store. Now that the lockdown is lifted there is still the line although not very long anymore.

What may be the reason for the line to the entrance of the store? There is the crowd control that they allow only 10 people in the shopping area. When one is done then a new shopper will be allowed to enter. The social distancing is causing all that inconvenience. That is the adverse effect of the corona virus.
