Thank You Lalmon, You are very right, everytime it's not my fault, I try not to include my insurance company, but in this case I had to, and I was not able to get rental car from them since I did not have that kind of coverage. But the ajuster told me that if I could rent a car then the at fault's insurance comapny would reimburse me if I could provide them the receipt.
So my question, is if I rent it from my friend can he write a recept and would that be a valid receipt eligible for reimbursement?
