I had a similar situation with an old operator a few years ago. He was being very generous and gave me all the machines in his storage locker, if I helped him clean it all out before the end of the month.
It was one of those deals- take it all, or nothing, and there were several dumpster candidate pieces for sure. There were also plenty of outstanding machines.
While I was loading one of the machines, I unclipped the bill stacker and it was jammed full of bills, and I don't just mean ones, and when I say jammed, I mean like a hefty stack. I already had the machine on my trailer, and technically we had our "all or nothing" deal, but I still walked over to him and handed him the wad of bills.
The guy was so happy he ended up giving me even more games from another location, one was a Last Action Hero pin, which I shopped, sold for 1K and then drove over and handed that money to him as a surprise.
Come to think of it, why did I do that again?
Oh, I remember, that damn Christian upbringing!
