I worked for a cell phone company and this older lady called in complaining she could not hear anyone. So after 15 minutes of troubleshooting (remember she is older) I finally asked her how she was holding the cell phone. Her comment like a your supposed to like a walkie talkie. Light bulb moment!!! Had to tell her it was like using her home phone lets just say that was pretty much it for the conversation she hung up. I have many more stories worked their 9 years!!
