This is a funny apocryphal story:
A lady driver repeatedly complained that her car wouldn’t run very well. It misfired, it was sluggish, wouldn’t pull the skin off a rice pudding, and drank petrol as if there was no tomorrow. But, every time the car went into the garage workshop and was tested it was found to be fine.
Finally, the garage sent a technician out with the lady to see if they could experience the problem. She was more than happy to comply, if only to get to the bottom of the problem. The mechanic walked out to the car with her and asked her to drive. She settled into the driving seat put on her seat belt, pulled out the manual choke knob to full on, and hung her handbag on it.
Lol!
