A woman passenger leaned forward and tapped the taxi driver on the shoulder to ask him a question.
The taxi driver screams in fear, loses control almost crashes into a lorry, mounts the pavement and screeches to a halt punching and hitting the steering wheel.
For a few moments afterwards neither the driver nor the woman say anything.
Then the driver says, "listen lady, Don't do that again! You almost scared the life out of me!"
The woman apologises saying that she didn't think that tapping his shoulder would scare him that much.
The driver replies:
"It's just that it's my first day on the job!"
"What did you do before?" asks the woman.
"Well!" replies the driver, "For the last 25 years I've been a funeral chauffeur!"
