"I have been yelled at by a client before. When I arrived at her house, she started yelling at me that I was two hours late and she missed her doctor's appointment because of me. She called me inconsiderate for not letting her know I was running late and threatened to report me to my supervisor. I was not late and was 15 minutes early. I showed her my watch, and she thought I had changed it since her clock said it was a different time. I showed her my phone, and then she looked confused. She then showed me her clock on her wall, which had stopped working, but she was unaware. I changed the batteries in the clock, and she apologized for yelling at me. Everything was fine after that!"
