My father owned a used auto parts
yard for a long time. He would often fix peoples cars for them. One time he did some repairs
on a young mans car in the middle of summer. The young man picked up his car and was away from the shop for a few hours before he called to say his air conditioner wasn't working. My father said he had not worked on the air conditioner and nothing he did would affect the air conditioner. The young man insisted it was my fathers fault. Being the nice guy my father was, he asked the man to bring the car back to the shop. The young man proclaimed "I can't the air conditioner is broken". My father sent a tow truck to pick up the young mans car. When the car arrived at the shop my father went to crank it but the battery
was dead. He charged the battery for a bit and then cranked the car up. He turned on the air conditioner and what do you know it worked. He called the young man and told him the news. The young man was excited and rushed over to pick up his car. He paid my father for the tow and got in his car. He never started the car he just sat there. About an hour later he walked in the shop and said his air conditioner was not working. My father had been watching the whole time. Being a patient man he walks out side and hooks the battery charger
up to the young mans car. My father cranked the car, turned on the air conditioner, and asked the young man to sit down in the car. The young man was amazed, the cars air conditioner had never blown such cold air.
