When I was staying in my room at a hotel, the door bell rang. I knew who he was because I had asked to have dry cleaning for my shirt in the morning. So the staff came to my room and brought my shirt. At that time, I was in t-shirt and underwear. I didn't wear pants then. So, before opening the door, I said in a loud voice, "wait a minute!" I tried to wear pants, and after that, I would like to open the door. However, after I said, "wait a minute" loudly, the staff came into my room by using a spare key! I was so upset. I could wear my pants and went to him, and I said to him, "I said, wait a minute". And he said "thank you". I was sooooo disappointed. As a staff of four-star hotel, I really want him to study just a simple English.
