For the most part (certainly not ALL) they are losers and pretty much not worth dealing with.
I tracked a former owner down once, (not easy) but with help from the local PD i got a hold of her.
The whole locker looked so neat and in order. But it was really dusty, no one had been in it for years.
Well the lady who have had the same locker for 8 years, had suddenly stopped paying for it, and was 4 months past due.
What i wanted to give back to her was wedding pictures, graduation pictures and papers. But also an ingraved bracelet that she had gotten from the mayor for some reason .
The PD tracked her down and i got to meet her, she was in her late 70's and had been admitted to a nursing home. And with no family knowing about her locker it went past due.
The moment i got there and showed her what i had, that is a moment i will never forget. She was so happy to see all her personal papers and pictures.
Well after that i have always said to the managers that if they want their stuff back they can contact me thru them. Well diden't that blow up in my face. This guy contacted me ad wanted this and that back, and i said no way. Papers and pictures are ok. But everything else is mine. If he wants it he can buy it back. Well this guy "dopehead" came to my door and was really threatning me and my family. I told him he had 2 min to leave or the cops would be called. He was yelling all the way to the car and said he would come back. I don't care about that dopehead anymore, as this was while i lived in Knoxville,TN. If he had come back, my little friend .357 magnum would be ready for him.
