I travel a lot in my work, and what I dislike about my job is eating alone. It always makes me feel lonely to see others laughing and talking. So, room service for several nights was a better choice for me. After having room service three nights at a hotel in Houston, however, I needed to get out of my room. Although the restaurant opened at 6:30, I arrived at 6:25. The waiter at the front desk made a comment(评论) about my “being there really early”. I explained my dislike of eating alone in restaurants. He then seated me at a lovely table and asked me whether I would mind if he sat down with me for a while. I was glad! He sat and talked with me about his career goals and the difficulty of being at work on nights, weekends and holidays. He said he hadn’t enough time to be with his family. After 15 minutes, he saw some customers at the front desk and excused himself. I noticed that before he went to the front desk, he stopped in the kitchen for a moment. Then another waiter came out of the kitchen and had a wonderful chat with me. Before I left that night, some other waiters, even the cook, had come out of the kitchen and sat with me! When I asked for my bill about one hour later, all the people who had sat down with me came over in a big group to my table, and presented me with a red rose. And I cried! What had begun as a lonely night ended as a beautiful experience. 48. The author asked for room service because _______.
