Employee: Alright, did you bring the deposit?
Student: Yeah, I did what you suggested: asked everybody to give me some money to reserve their space on the bus. They know they'll have to pay more once we know what the total is.
Employee: I will have to run a few numbers to get the final cost. Vans are a lot cheaper than buses but we'll have to pay for 2 drivers. They'll charge us by the hour. Of course you will get the normal student discount from the van company and I'll deduct your deposit. I can let you know the balance tomorrow.
Student: Great, I'll come by after class.
