non paying customers .

Many moons ago, before I got into the parts business, I worked for a electrician.
We did a job at an apartment complex for the elderly. The property mgr decided, on her own, that Rick was over charging. She refused to pay him. I don't know what her reason was, but I remember Rick getting in the van PO'd. As we drove down the road and you could just see he was cooking. He turned around, went back and he pulled every meter to every apartment we worked in.
I remember him saying "that ***** can explain to her tenants and Duke why she's missing meters"
Not legal, and I'm not sure how that turned out, but at the time it was funny as hell.
