“Check it again, you need to be sure.”This culture rule may sound , but it is one of the most powerful culture rules. I took a lot of things for granted. In fact, I used to people who often check things, such as their car engine oil, the house security, even the children in the bedroom. I didn’t realize that this rule would cost me dearly. One day the owner of the supermarket I worked in asked me to make a(n) to the investors(投资者) whom we wanted to become partners with. I was given a month to it. The day of the presentation arrived. I left home at 7 am with the intention of getting to the office . On the way , my car climbed over a bunch of rocks and I heard a loud noise. I stepped on the brake and got out of the car to check what happened: I had a flat tire. “Oh dear, please not now .” I quickly ran behind the car to the spare tire, only to be again :there was none. I began to think of the moments when my wife would me to get one each time I drove the car out. But I was too to listen to her. It was already 8 am and it seemed like I had only one left. I had to run to the supermarket. It should me about 45 minutes to get there . I the car and ran as fast as I could , hoping I would have the to get there on time . it took me longer than I had expected. I arrived at the twenty minutes late. I to the guests for my lateness and did my best to give a good presentation. Finally, the supermarket the deal, but I was suspended(停职) for two months without pay.
