You're at a dinner with friends when someone's (maybe yours) cell phone buzzes. Annoying? For sure - that's why there's a new game called "The Phone Stack" that aims to solve this social rudeness problem:
Also known as "Don't Be A Di*k During Meals With Friends," the game tries to curb cell phone interruptions when dining out with pals. After everyone orders, they place their phones in the center of the table, face down. They may even stack the gadgets, as the name suggests. Even as the phones buzz and ring throughout the meal, no one is allowed to grab his device. If someone is unable to resist his smartphone's siren's song, he's responsible for picking up the check.
When it comes to manners answering your phone when in company sends out a clear message that you think the person on the phone is more important than the people in your company. As such I tend to just get up and walk when somebody answers their phone in my company. If they're not interested in me, then I'm not interested in them.
A while ago we were in a group of six in the pub when one of our number answered their phone. He stood up and walked to the other end of the bar to take the call. Without any discussion the rest of us finished our drinks and headed for the next pub.
