I am a small welder repair shop and I had a customer bring in a machine on Feb 27, 2019, to be repaired. He brought his own part (which was used) and it did not work. He said he would purchase a new part, so we removed the old part for a second time. I have had to payout for labor and his equipment is still at my shop. I have sent him a notice through certified mail and he said he would come and pay the bill and pay for labor and storage. To date it is over $1,300.
