To be honest, if people are stupid then further lockdowns will follow. It's in our hands here. Act sensibly and we can live a relatively normal life over winter. Act like knobs and we'll be back to being heavily restricted.
I barely drink and what time the bars close is fairly irrelevant to me. But I think its absolute madness if they think everyone just goes home. They are going to cause lots of house parties, the thing they say is worst for spreading the virus.
