A passenger in a taxi reached forward and gently tapped the driver on the shoulder.

The driver screamed, nearly veered into the ditch and came to a stop just short of a building.

The shaking driver said are you OK? I am so sorry, you scared the daylights out of me.

The badly shaken passenger said “I’m sorry, I did not realize that a mere tap on the shoulder would startle someone that much.

The driver said “No No it is me that is sorry. It is entirely my fault. Today is my first day driving a cab, I spent 25 years driving a hearse.
