Last summer, I got a part-time job like a waiter. I worked hardly and was very helpful. Everyone in the restaurant including some regular customer liked me. One day, a foreign couple, which were in their fifties, entered the restaurant. I was happy to have a chance to practice my spoken English. I went up to greet them warmly. After I took their order, I told them their food will be served quickly because us Chinese respect the elderly. Hearing my words, a look of displeasure was appeared on the wife’s face. Seen my confused look, her husband explained to me the westerners disliked the description “old”. I made a apology to them, keeping in mind the lesson cultural differences should never be ignored (忽视).
