During Covid the government never said anything at all was "safe". All the language used was about risk, i.e. lower risk, etc. They certainly never said it was "safe" to go out and have restaurant meals indoors.
Yes, idiotic Rishi encouraged "eat out to spread covid" but again there was nothing in that to say you had to go to eat in crowded unventilated indoor restaurants. People could have used common sense and avoided the busy times or only gone to places where they could eat outside.
It's ALL about personal responsibility, weighing up risks, making your own decisions according to your own circumstances, i.e. your own health, medically vulnerable people in your household etc. So, basically using common sense.
Government should be restricted to telling people the data and giving them enough information to make their own decisions. Nowhere else with public health do they "ban" you from doing something. People weren't "banned" from smoking, eating McDonalds burgers for every meal, drinking a bottle of gin every day, etc.
