I used to work at Kmart in the auto dept. back in the early 90's. People used to do that all the time. I had a guy
actually ask me a question about a part, worth maybe $25. About 10 minutes later I was called up to the service desk
to approve a no receipt return (as was standard practice), well here is this same guy, with that exact part asking for
"his money" back. Didn't matter how hard I fought it, the manager still came up and OK'd it with no questions
asked. One of the funniest returns were when I worked in the paint dept and some quy would return the paint
container filled with used motor oil and chunks of Styrofoam in it to prevent it from sloshing around too much. Happend
about a half dozen times, then they finally started opening the paint up at the return desk.
I'll say this, if these people spent half the time they spend on these scams for good, not telling what they could do.
