Cell phones!! We have signs all over our office to Please Turn Off Cell Phones--they interfere with some medical equipment. Out in the waiting room, of 4 waiting, 2 are talking away. I called one of them back to the exam area and she holds up a finger to tell me "one minute". Well, you know what finger I wanted to hold up!! I called the next patient and she acted all huffy. Oh well, lady-learn some manners and learn to read!!
What is so important that you can't shut off a cell phone for an hour?
