雅思口语P2 Describe a situation when you had to be polite（文字版）

I can’t recall the name of this person but he was around 40 years old. On the date of job interview, I reached the office and I was completely wet because a hard rain hit me on the way. I could not wait somewhere scaring that I would be late for the interview. After I got there, he asked me to wait in the conference room and did not show up in next 30 minutes. After that I handed him the papers very politely and he was very much annoyed because he could not find the original certificates. I told him that I was required to bring the copies. I also assured him that I can provide the necessary documents anytime he likes. He got even angrier when he noticed that my clothes were wet. He did not even offer me a dry towel or something like that. From the very first moment I met him, I disliked him. He was mean, rude and unfriendly. When he told me that I was not properly dressed for the interview indicating my wet shirt, I first wanted to leave the office immediately. However, I didn't do it in that way. I finally got the job, but it was a hard time to go through.
