The mistake you made was: being on a bus, the bottom of the public transport pecking order (speaking as someone who went carless 20 months ago). Were they also vaping and playing tik tok videos out loud? There’s your answer.
Also, what others have said about people being detached from the natural environment. If someone can’t think to check the weather and sunset times before, say, going up Helvellyn, are they going to do it when they walk to the shops?
