My part-time job

I have a part-time job, and I work three times a week. My job is working at yakiniku restaurant and I usually take the dishes to the customers' table, remove them from the table. After closing the restaurant, I clean the floor, wash a lot of dishes and the hot plates and so on. Finally, I can go back home at about 0:00 a.m. I think it was very exhausted job, but I am glad when I see smiles of many customers. It makes me happy! (1982)
