Adam your life is irrelevant to any situation. Stop trying to find a middle ground between Otis and your finger fuck buddy Nathan. Obivously Nathan hasn't made a professional movement towards this situation when you "own" a business you are responsible for all the activities that happen in the shop especially when you have no lis. Why? Because if Otis did take him to court Nathan would have his asshole like a 4in downpipe of how much fines he would get. Why do you think you sign paper when you leave your car and then take your car from a reputable shop? Because it covers them incase of any mishaps. So what's gunna happen? Here is my prediction either Nathan pulls the parts out of his ass or get Otis the money he owes him.
