Early stages of this video shows one of the most annoying issues with public transport today, people (usually younger folks) playing their crappy music out loud on crappy sounding phones. None of them seem to own head phones or earphones these days. The other big one, and this time it's mainly the adults, is that people today don't seem to know how to have a private phone conversation. They use video calling and proceed to shout at each other so we all have to put up with it. Noise cancelling headphones or earphones are a must for anyone who uses public transport regularly these days.
I Have lived in NSW Australia for over 40 years brought up in Kilwinning interested to note how much has stayed relatively untouched in the village centers in that space of time.
