W: Hey, Dave! I haven’t seen you for ages. How have you been?
M: Oh, I’m doing okay, but school has been really busy these days, and I haven’t had time to relax.
W: By the way, what’s your major anyway?
M: Hotel Management.
W: Well, what do you want to do once you graduate?
M: Uh... I haven’t decided for sure, but I think I’d like to work for a hotel or travel agency in this area. How about you?
W: Well, when I first started college. I wanted to major in French, but I realized I might have a hard time finding a job using the language, so I changed my major to computer science. With the right skills, landing a job in the computer industry shouldn’t be as difficult.
M: So, do you have a part-time job to support yourself through school?
W: Well, fortunately, I received a four-year academic scholarship that pays for all of my tuition and books.
M: Wow. That’s great!
W: Yeah. How about you? Are you working your way through school?
M: Yeah. I work three times a week at a restaurant near campus.
W: Oh. What do you do there?
M: I’m a cook.
W: How do you like your job?
M: It’s okay. The other workers are friendly, and the pay isn’t bad.
