There are always people that will complain if you even give them the item. Years ago we had a customer come in with a hydraulic cylinder with a bent 1/2 inch rod. He told us he needed it quickly. Made him a new rod and resealed the cylinder. He came in and was screaming that he just wanted the rod straightened and he wouldn’t pay for it and would just go purchase a new one. Came back the next day and paid for it. Repair was only $175 and a new one was $1700. ( JD Green).
