Fairly lengthy train journeys recently, we booked the quieter coach well in advance, because we like to read or quietly look at the scenery. On the outward journey there was a man holding various face time conversations quite loudly. The woman sitting in her booked seat next to him was getting really fed up, and eventually moved. The younger guy behind us kept playing bits of music on his phone.
Coming home, the first part of the journey was bliss. We changed trains, and the two passengers behind never stopped yakking loudly. Why would anyone book a seat in a quiet coach only to be noisy? No staff around once the tickets were checked, and we are older and don’t wish to risk a confrontation. Twenty years ago my younger and healthier DH might have said something, but not now.
