W: Is this the right line to file a claim?

   W: Oh. Is there always such a long line?
   M: Every week. Sometimes longer. Is this your first time here?
   W: Yes.
   M: What happened? Your plant close down?
   W: No. I’m a car salesperson, or, I was a car salesperson. But we just aren’t selling cars. It’s the interest rates. Two years ago, I averaged ten new cars a month. Do you know how many cars I sold last month? One. One car to a lady who had the cash. But the interest rates are up again. The boss let three of us go. How about you?
   M: I worked at a vacuum cleaner plant with about fifty workers. We put in a good day’s work. But the machinery was getting old. As a matter of fact, the whole plant was old. So the management decided to build a new plant. You know where? In Singapore. The workers here made about seven dollars an hour, a couple of people made about eight or nine an hour. You know how much they’re paying the workers in Singapore? $ 2. 50 an hour. Who can live on $ 2. 50 an hour? Anyway, all fifty of us got laid off.
   W: How long ago was that?
   M: They closed down ten months ago.
   W: Any luck finding another job?
   M: Nothing. I have one, sometimes two, interviews a week. Last week I thought I had something. They liked my experience with machines. But I never heard from them again.
   W: At least you know something about machines. All I can do is talk.
   M: Maybe you’ll talk yourself into another job. Good luck. I’ll see you here next week.
   W: I hope not. I hope I’ll have something by then.
