Difficult. I think that businesses that intentionally ignore mask mandates should be forced to close if they are repeatedly caught not asking customers to wear a mask. However, the government basically made basic retail workers play police. If I were working in a shop and someone would show aggression toward me when I try to enforce mask mandate, even if I exercise the domiciliary right if the business, I would not ask again and risk a dangerous confrontation. That’s not my fucking job.
