There is no excuse here. I give two shits what the repair cerner's policies are about cleaning the equipment, etc. It was obvious that the writing and artwork was there ON PURPOSE!

If it was me, I would find a way to put a monetary value to the signatures and picture. Something like the cost of the trips I had to take to gain the sigs and drawing, etc. Then file a lawsuit. Those people need to be hit in the pocket hard.

Although, if it was my case, I would have had it clearcoated or something to help preserve the ink!
