Hypothetical question

If you could choose how to charge for late books, would you:

a. Charge a fine per day until the amount reaches the maximum fine. If it is still not returned after that time period, then the replacement fee would be charged.

b. Return it and there would be no fines (!). BUT,  if it is damaged or lost, you would have to pay the replacement fee. Also, if the book is recalled and you did not return it, there would be a fee of maybe, $1.00 per day.

–I see benefits and problems with both sides.

I would probably pick “b” though, if I had the choice.

Any thoughts?
