M: Hey Linda, do 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.  Instead of paying one fee to cover all meals for the whole school year, we’ll now be able to choose how many meals per week we want and can contract for just that amount. We still have to pay for the whole year at the beginning of the year but we can choose to buy seven, ten, fourteen or twenty-one meals per week.
W: That’s a big change, Tom.
M: Yeah. It will be much better for people who don’t eat three meals a day, seven days a week in the cafeteria because they won’t have to pay for meals they don’t eat.
W:  So what’s the meal for those who do eat at school all the time?
M: It’s better for them, too, because the more meals you contract for, the cheaper each one is.
W: I see. It still sounds rather complicated.
M: True, it took me several hours to figure it out:
W: What’s your meal plan?
M: I decided to go with the ten-meal plan. I never eat breakfast and I often go away on weekends. So I won’t pay for meals I don’t usually eat.
W: But what about the weekends when you are on campus?
M: Well, there are often guests on campus on weekends. They are allowed to buy single meals on Saturdays and Sundays. The price for meal is much higher that way. But it will still be leas money for me to pay than sign up for the fourteen-meal-a-week plan.
W: Hmm, I guess I’ll have to sit down and figure out my eating patterns.
