Opposing point of view here... it wouldn't be the first time somone got over zealous, and arbitrarily claimed "You're paying for this!" in either some misguided attempt "scare" the member staight, or for reasons of their own personal inadequacy.
I did some minor cosmetic damage to a DND vehicle some years ago as a private (For what it's worth, it was determined that I was not in any way negligent, and the cause was both a fault in the vehicle, and a very poorly placed steel hand rail on a stair case.... which had alredy been struck by multiple other vehicles.).
Shortly after (the next day or so) I was summoned to our local base transport section, where I was given a good two hour blast from several MSE ops of ranks between MCPL and WO about how I was a terrible driver, how I was going to be charged, and how I was going to be held fully responsible for the full amount of repairs (which was the cost of a new bumper, I believe it was abuot $1700, no small sum to a class A reservist).
Ultimately, I was not held responsible for any of it, and I got my 404s back within a week, no charges, not even any remedial training.
At the time, I was appropriately frightened that I would be paying $1700.
In retrospect, , the MSE section, while they did conduct the investigation on the damage, despite their ranting, had no authority to charge me, or collect any money, they can make all the recommendations they like in their report, but the authority to charge and fine lies with the CO.
