Dont loan out your tools

But seriously, Folks.
It all depends.
Sometime we borrow things.
But I can tell you that (most all without exception) aircraft mechanic will hunt you down like a dog if they even happen to pick up your tools by mistake to return it to you. Plane jobs are routinely preformed by a group of people.
One thing you don't want people to think about you in aviation, you steal.
Maybe it's not like that in car dealership shops?
Just saying.
