A customer bought a new car, he always used to go to a particular ice-cream shop. he doesn’t have any problem whenever he eats vanilla ice-cream but when he eats strawberry ice-cream the car will have starting trouble. He reported this to the car company the mechanical checked and reported that the car has no problem. The next day customer got the same problem when he ate strawberry ice-cream at last an intelligent mechanical found out the reason.
Can u guess what?
