tapped him on the shoulder.
The driver screamed, lost control of the cab, nearly hit a bus, drove
up over the curb, and for a few moments everything was silent in the
cab. Then the still shaking driver said, "I'm sorry but you scared
the 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. I'm
new to this. Today is my first day driving a cab. I've been driving a
hearse for the past 23 years."
