I have a loaner tool box then a tool box I gaurd with my life and if you value yours dont borrow from mine.
Dont ask to restore your car in the back of my shop.
Dont whine about your foot being burnt by slag from a torch when you stand there wearing flip flops in a shop.
I lost a friend over loaning the back of my shop out to a friend for car restoration. Had a friend thathad a 66 Mustang and wanted to put a motor and transmission in it. I said yes, and on Friday I come home to 8 folks I dont know working on his car and anothers pick up. They had put the motor in and had the thing on blocks sanding and working saying they were restoring it. Later I talked with him and he said it would be few days and no more friends there. he didnt touch it a few weeks and I had a big job come in the shop. I griped at me about rolling his car to the side bay. That flew all over me I took the Hyster and shoved the car out side and put all his tools in the floor board.
