Why can’t Peter relax over the three-week vacation?

Crystal　　Hi Peter-I’m so pleased that exam’s over!
Peter　　　Me too, Crystal-I’m exhausted. I stayed up late last night studying and then got up
　　　　　 early this morning.
Crystal　　Well, you can rest now-we’re on holidays for three glorious weeks.
Peter　　　That is a nice thought. Unfortunately though, I’m broke and if I’m going to have
　　　　　 enough money to get through next semester, I’ll have to get a job over the holidays.
Crystal　　Yes, I’ve been thinking the same thing myself. As much as I’d like to go home
　　　　　 to see my family, I think I’ll have to get a job as well. Have you got any ideas or
　　　　　 contacts?
Peter　　　Well, as a matter of fact, I’m going to go to the Student Employment Office. Do you
　　　　　 want to come with me?
Crystal　　Sure, if you don’t mind. Where is it?
Peter　　　Let me see-(TAKES OUT PAPER)-I’ve got a map here of the campus. It’s up
　　　　　 here in Y Block.
Crystal　　Oh boy-we’re a long way away from there! We’ve just come out of N Block-
　　　　　 here we are here.
Peter　　　Yes, N Block. Well, we can turn right and follow Circular Drive around but that’s
　　　　　 the long way. What’s the building opposite us?
Crystal　　That’s the International Centre-I learnt English there before starting my Bachelor
　　　　　 of Business.
Peter　　　Oh right-I see, it says I Block. I guess I stands for International. Well, let’s cross
　　　　　 Circular Drive and walk up to the right...
Crystal　　No, there’s lots of trees and gardens there-we’d better go to the left of the building.
　　　　　 You can’t get through otherwise.
Peter　　　OK-we’ll head past D Block, go between B and C Blocks and then across the
　　　　　 sports fields to Y Block.
Crystal　　OK, but I’m really hungry. How about going to the student canteen before we get to
　　　　　 Y Block? It’s just on the other side of A Block-near the main entrance.
Peter　　　Good idea-I didn’t have breakfast this morning. I’m starving! Let’s go.
