What’s the main feature of the new method of paying for meals?

M: Hey Linda, did you get that letter about the new options for food service next year?
W: Not yet. Are there a lot of changes?
M: There sure are. (1)Instead of paying one fee to cover all meals for the whole school year, we are now able to choose how many meals a week we want.
W: That’s a big change, Tom. So what’s the deal for those who do eat at school all the time?
M: (2)It’s better for them too. Because the more meals you contract, the cheaper each one is.
W: I see.
M: I decided to go with the ten-meal plan. I never eat breakfast and I often go away on weekends. So the ten-meal plan gives me lunch and dinner every weekday at a fairly low price.
W: And what about the weekends when you are on campus?
M: Well, there are often guests on campus at weekends. (3)So they allow you to buy single meals on a walk-in basis on Saturdays. The price per meal is much higher that way, but it is still favourable generally.
W: Oh, I guess I’ll have to sit down and figure out my eating pattern so that I can get the best deal.
