I hate places that try to dictate rules to me. I'm not in the service nor the first grade anymore. Tell me I have to turn off my cell phone, and I'll turn it on just to irritate you.
It’s about common courtesy. Do whatever you want as long as it doesn’t affect me. The minute your inconsiderate actions affect others it’s a problem. Some people will tolerate the nonsense and some won’t. Unfortunately the ones who tolerate it only embolden the obnoxious ones to be even more obnoxious.
