When I was in the Navy, NAS Miramar, San Diego, I had a part time paying job at the base auto hobby shop. One day I came in, went out into the yard to look around at activity, and here's a kid under a 57 Chev. You all remember the big bumper "tits" on those. Here he was, feet sticking out, and a bumper jack jammed up against each bumper tit, and not a jackstand in sight. I went over, grabbed him by his ankles, and yanked him out of there. He wanted to fight. He was in dungarees, and had no "crow", so I knew he was only E2-E3. I was E5. I told him, "you have no idea what and who I am, but I know what you are. I can fix it so you cannot come in here. You have two choices---either go up to the tool room and check out a pair of jackstands, or pick up and get out of here."
So he went and got jackstands. Thing is, back then, you payed a nominal amount to get in there, but you could check out all kinds of tools, free. When you got your stall, you got a ring of about 10 or 12 tags with your stall number. You just went up to the tool room and told them what you wanted. We had wrench sets or socket sets on a board, 2 or 3 floor jacks, and lots of jack stands
