I have had two bad interactions with people and groups at two different locations, people are the real danger in the UK.
Two woman in the local large shopping car park, being aggressive shouting at people for having full trolleys, very angry uneducated rats looking to blame everyone else for them not preparing.
80+ man was in the local shop shouting at people randomly for shopping and calling fat people the problem and they didn't exist in the War. It was really sad I called him Albert from only fools and horses and walked away.
Prepare for the worst, hope for the best, because hope is not a strategy.
