Worst I've seen was someone casually standing guard at the adjacent locker as we arrived. After a minute a woman with too much makeup and a businessman emerged from their nooner and drove off.Basically I'm a hobby welder, tractor stuff and yard art.
Never refuse to do a minor repair for friends either.
But then I have done the odd 'paying' job but even that was mostly for the challenge than for money but it does help pay for supplies.
2 examples are converting 4 post car lifts into freight elevators and also fabricating a dozen 'luggage' type carts for my friends storage facility.
Whenever we'd find a deal on 6 inch casters we'd scrounge metal and make up 3 x 6 ft push carts for the tenants to move in or out their goods.
LOL, he'd buy my lunches and I'd often get 'pickings' from closed out lockers.
Amazing the great things tenants would abandon rather than pay their rent.
I've seen everything from perfect power tools thru to broken furniture and everything in between.
The worst and most cumbersome is mattresses and probably old Xmas decorations with clothing in between.
The look on his face said we interrupted them too soon.
Sorry bout that!
