Tap on the Shoulder

A passenger in a taxi leaned over to ask the driver a question and tapped him on the shoulder.The driver screamed, lost control of the cab, nearly hit a bus, drove up over the curb, and stopped just inches from a large plate glass window. For a few moments everything was silent in the cab, and then the still shaking driver said, "I'm sorry but you scared th e daylights out of me." The frightened passenger apologized to the driver and said he didn't realize a mere tap on the shoulder could frighten him so much. The driver replied, "No, no, I'm sorry, it's entirely my fault. Today is my first day driving a cab. I've been driving a hearse for the last 25 years."
