Mind your own damn business and I'll do the same. If I'm carrying a phone to a nice restaurant, it's because I'm on call. No, I do not raise my voice to talk, because I've mastered the arcane art known as "volume settings".If my phone rings, there's a high likelihood I won't be there for long anyways. And in the meantime, if me texting at my own table bothers you, or a couple of low volume buzzes bother you, I highly suggest you disinvolve yourself in the actions of other people's personal lives. Failing that, I invite you to attempt airborne fornication with a gyrating piece of pastry.

More on topic, how much do you want to bet this is just an excuse to raise prices by 5%? Furthermore, the day I give my phone away to some random in a restaurant is the day I've taken full leave of my senses.
