Public sentiment around loud phone conversations is strong, with surveys indicating that a significant majority of people find loudspeaker use unacceptable in shared environments. Various countries have adopted different protocols for managing noise on public transportation. For instance, UK train operators have implemented "quiet coaches" to maintain tranquility, while similar practices are endorsed in Italy and Japan, where loud conversations are viewed as discourteous. In South Korea, passengers are encouraged to keep voices low and phones on vibration mode. As etiquette evolves, the incident at Nantes station reflects wider tensions over noise in public spaces worldwide.
