United Airlines has banned the use of mobile phones playing audio/video contents without Headphones. Should have been done by every Airline, Railways, Bus Transportation System etc. long back. Not only them, but playing audio-video contents on mobile phones at public places without headphones should also be banned at Coffee Shops, Restaurants, Public Places. People playing YouTube Reels, Videos, Instagram blabbering, at public places without using Headphones, anticipate that the person sitting or standing next to him/her would also enjoy their brain rot, or, 24/7 commentary videos. And as you cannot argue, you end up vacating that seat or place only.
