M: Hey Linda, did you get that letter about the new options for food services next year?
W: Not yet. Are there a lot of changes?
M: There sure are. Instead of paying one fee of all meals for the whole school year, we will be able to choose by seven, ten, fourteen or twenty-one meals per week. They give you a card with the number of meals for a week marked on it
W: That’s a big change. And a complicated system.
M: Yeah. But it will be much better for people who don’t eat three meals a day, seven days a week in the cafeteria because they don’t have to pay for meals they don’t eat.
W: So what’s the deal for those who do eat at school all the time?
M: It’s better for them too. Because the more meals you contract the cheaper each one is.
W: I see. Still sounds complicated.
M: True. It took me several hours to figure it out. I decided to go with the ten meals.
W: Why is that?
M: Well, I never eat breakfast and I often go away on weekends. So the ten-meal plan gives me lunch and dinner each weekday at a fairly low price.
W: And what about the weekend when you are on campus?
M: Well, there are often guests on campus at weekends. So they allow you to buy single meals on a walk-in basis on Saturdays and Sundays. The price per meal is much higher in that way. But it will still be less for me to pay single prices on the weekends rather than sign up for the fourteen-meal-a-week plan.
W: Oh, I’ll have to sit down and figure out how I can get the best deal.
