单选题根据以下材料，回答题
When my family moved to America in 2010 from a small village in Guangdong, China, we brought not only our luggage, but also our village rules, customs and culture. One of the rules is that young
people should always respect elders. Unluckily, this rule led to my very first embarrass- ment in the United States.
I had a part-time job as a waiter in a Chinese restaurant. One time, when I was serving food to a middle-aged couple, the wife asked me how the food could be served so quickly. I told her that I had made sure they got their food quickly because I always respect the elderly. As soon as I said that, her
face showed great displeasure. My manager, who happened to hear what I said, took me aside and gave me a long lecture about how sensitive Americans are and how they dislike the description
"old". I then walked back to the table and apologized to the wife. After the couple heard my reason, they understood that the problem was caused by cultural differences, so they laughed and were
no longer angry.In my village in China, people are proud of being old. Not so many people live to be seventy or eighty, and people who reach such an age have the most knowledge and experience.
Young people always respect older people because they know they can learn from their rich experience.However, in the United States, people think "growing old" is a problem since "old" shows
that a person is going to retire or that the body is not working well. Here many people try to keep them-selves away from growing old by doing exercises or jogging, and women put on makeup, hoping tolook young. When I told the couple in the restaurant that I respect the elderly, they got angry be-cause this caused them to feel they had failed to stay young. I had told them something they didn't want to hear.After that, I changed the way I had been with older people. It is not that I don't
respect the many more; I still respect them, but now I don't show my feelings through words.By Jack
Jack brought the couple their food very fast because______

A． the manager asked him to do so
B． he respected the elderly
C． the couple wanted him to do so
D． he wanted more pay
