Do you have a right to reasonable charges for damage of rented items? If you rent a jackhammer and break the trigger is it fair to charge the customer five hundred dollars to repair a ten dollar piece of plastic? If you rent a wedding dress and rip a seam should you be expected to pay a fashion designer for the stitching? Nobody would ever rent anything if every object was a minefield of potential absurd over-charges.
