people that want to spend time with you but then end up on their cells part or all of the time. I understand that you have other things to do in life but I don't want to feel like part of a to do list. I put mine on vibrate so should you.
Also parents that tell their children not to use double negatives and then utter something like "them there sammiches don't need nothing else on them". I wonder where your child gets it.
ordering when you are on your phone. This is the single rudest thing ever. Don't complain if your order is wrong if you can't even get off of your phone.
