I cut myself skinning Bobcat. Tested by state, (PA) test was negative. I was tanning bobcat for customer and he wanted me to save the skull for him. Once I cut myself I felt it necessary to have it tested. The state won't return anything tested. Now customer is pissed that he isn't getting skull back. I offered to get another one and will clean and whiten. Originally I was supposed to just save skull, not clean and whiten. Still pissed. He wants to contact the state and get his back. We're talking 6-8 weeks ago. There's no way he will get his back. I will offer again to get another skull. He still owes me the balance of tanning bill. Any advice on how to proceed.
