The vast majority of people in Prague are really good about following orders. They don’t like them but they know that following the rules works. It’s why despite everything else becoming shit, Prague has been getting worse at a far slower pace than the rest of the country. It’s the people outside of it bitching about masks and actively breaking the rules that are the problems. It’s why the places with the most cases/100,000 are rural bumfuck areas of the country and not Prague.
Thing is that the current PM gets most of his votes from rural areas of the country. He and his party are popular in those bumfuck areas and him doing these things is making him less popular there. It’s why he held off on implementing safety measures until the Senate and Regional elections. He needed their votes to gain more power at the district level.
