So, back maybe 20 years ago, I met a very friendly couple, new to the area, at work. We talked and they made a purchase, then returned a few days later for another purchase. What a nice couple!
Then, their checks bounced (this was back in the day when I still accepted checks). I assumed it was an accident, since they just moved to the area and were probably switching over their banking, etc. I told my business manager to wave the NSF fee; I was certain they’d be in with apologies right away.
Days and then weeks passed with no contact from them. I tried calling and eventually got through to a machine. I left a polite message, blah, blah. No money. One day I called and the guy answered. He explained that he felt bad, because I was a nice guy, but I’d never see the money, as it was a planned thing that he and his wife had done for years. Sure enough, looking things over, the two purchases were strategically separated to keep the check amounts each below what I could turn over to law enforcement.
A month after that, during a snowstorm, I had to run in to work for a minor emergency. The snow was really coming down, but I was in four wheel drive with monster tires, so I took the scenic route home, driving a back-back-back road that was red-dog and totally untouched by snowplows.
At about the halfway point I saw a minivan with a flat tire. The driver had pulled over to change it, but the berm was a ditch and the van’s one side was down in it. I had a good jack in my Jeep and figured I could raise the vehicle up, pull the van back onto the road, or at least take the people into town.
I stopped my Jeep and immediately recognized the couple. Once I was certain they recognized me, I drove off, leaving them stranded and the weather rapidly worsening. There would likely be no traffic on the road overnight, so one or both of them would be walking 3-4 miles to reach “civilization”.
TL;DR: Karma, if it exists as an entity, works both ways.
