One day, the Pontiac department of the US General Motor Company received a customer complained that he wrote this: "This is what I write for the second time for the same thing, I will not blame you why I didn't reply to me, because I also think that others will think that I am crazy, but this is indeed a fact. "" Our family has a traditional habit, which is that we will take ice cream after eating dinner every day. Sweets after meals. Because of the taste of ice cream, our family will only vote for a taste every day, and I will drive to buy. "" But since I bought a new one after you have recently I have bought a new one. " After Pang Diji, I happened when I went to buy ice cream. "" Do you know? Whenever I bought the ice cream is a vanilla taste, I can't do it from the store. But if I Buying other tastes, the car is going to be very good. I want you to know, I am very serious about this matter, although this problem sounds very pigt. Why do this Pang Diji I bought a vanilla ice cream? It doesn't do it, and I don't care when I bought ice cream, it will live a live dragon? Why? Why? "
In fact, the general manager of Pang Diji is really skeptical about this letter, but he also sent an engineer to see exactly. When the engineer went to this friend, it was surprised to find that this letter was a successful, optimistic, and higher education. The engineer arranged with this friend's meeting time just after using the dinner, the two had a arrow jumped into the bus and opened into the ice cream. The result of the evening voting is a vanilla taste. When you buy a vanilla ice cream, the car is not moving. The engineer has been rely on three nights. On the first night, chocolate ice cream, the car is fine. Second night, strawberry ice cream, the car is nothing. On the third night, vanilla ice cream, the car can't move. This thinking of logical engineers, is still allergic to vanilla. Therefore, he still does not give up the same trip to continue to arrange, and hope to solve this problem. The engineer began to note the details of the peaks from beginning to now, such as time, the time of the car used oil, the car opened and opened back ..., according to the information, he has a conclusion, this friend bought a vanilla ice cream. Time is less than other tastes.
why? The reason is the problem of internal settings in this ice cream shop. Because vanilla ice cream is the best-selling taste in all ice cream tastes. In order to let customers come to pick up the vanilla taste in a separate freezer, place the freezer in the front end of the store; The taste is placed behind the rear end of the cashier. Now, the questions you have to know are that this car will not move because of the shortest time from the extinguishing to reactivate? The reason is very clear, it is definitely not because of the relationship between vanilla ice cream, engineers quickly appear from the heart, the answer should be "steam lock". Because when this kind of brother bought another taste, due to time, the engine had enough time to heat dissipation, and there is no big problem when re-launch. But when you buy vanilla taste, due to the short time of spending, the engine is too hot to have sufficient heat dissipation time.
