Installing such equipment will reportedly to cost about $7,300 (6,000 euros) per instance but appears set to win priceless levels of customer satisfaction, with surveys showing overwhelming support in France for the measures that address.

Kevin Spacey, a Hollywood actor and now artistic director at London's Old Vic theater, recently criticized British audiences for failing to switch off their phones during performances.
"You have to respect the fact there is some degree of behavior that we expect in the theater, and we're going to demand it at the Old Vic," Spacey told BBC Radio 4 last month. "It's a phone-free zone. We don't want them ringing, and we certainly don't want them ringing and people ignoring them, pretending that it's not theirs."
