1. I'll put my phone on vibrate for you. Remember this handy little function? Vibrate allows you to feel the calls without interrupting everyone in the room with Beyonce's hit song "Single Ladies". This function can best be put to use when at dinner with friends, in class and at work, or on the bus. "On a Boat" may be your summer theme song, but others may be in a different zone.
Two more, after the jump.
2. To text or not to text. Similar to how slurping in some countries is considered a compliment; there are some places where texting is rude. Different places and people set the bar at different levels. If you're unsure if sending a quick message to a friend, ask if it's OK to whip out the phone.
3. Talking while ordering. Speaking from personal experience, I know cashiers certainly don't like it when people order their food while talking on the phone. Put down the phone and talk to the person who holds the fate of your burger in his or her hands. Not only will they appreciate it, but I guarantee they will hold the spit.
