Stop in for a cup of coffee

I guess I just don't understand the business model for a paint and body shop. I did my best to try and get a solid relationship with owner. I paid cash and explained I really did not need paperwork just wanted car back as promised. That was a couple two or three deadlines ago. Not sure how he can point at a couple cars that were not on lot at last visit and explain Demon will be right after them. I am just not going to stress over it as this topic will wind me up like a clock. If I ran my business this way I would be tits up in no time.
