"Jan, you are assuming that:
1: the lady did not want to sell the camera originally
2: the guy did not tell her that the gear is all fine.
None of these two are detailed in the original post."
Pherdinand,
Of course you are right, he doesn´t mention this in his original post. But then again, he doesn´t say if and how he helped her to check the gear was fine. Nor is it clear if the lady went into the store with an idea of selling, as far as we know she couldn't get it to work and that was the main reason she addressed the salesperson. We obviously don't have all the details to judge and maybe I'm assuming things that are not so. But it still feels wrong to me.
A friend of mine works in a camera store. He doesn't own the store, he's just an employee. One day I was there looking into some second hand Nikon stuff they had for sale, a guy walked in with a Nikon F801 (N8008 in the US). Same story, couldn't get it to work. My friend checked it, popped out the four AA batteries and put them back in. Turned out that one of the batteries was put in the wrong way. The guy walked out as a happy customer.
If I walk into a store with something that I can't get to work (be it a portable computer, a cell phone, whatever), I do so because the person behind the counter should have a better understanding of it than I do. It doesn't matter if I bought it there orginally or not, I expect the salesman to be more knowledgeable than me. As a result of this, as a customer I trust that the salesperson knows if it can be fixed or not, and if I wanted to sell it, what it would be worth in working order or broken.
I've had my share of incompetent camera salespeople, who couldn't tell the difference between an f/2.0 and an f/2.8 lens. Needless to say, I'd never buy in these places nor trust the advice given to me, but that is because I know more about cameras than this so-called salesperson did. In this case here, it looks to me the other way around: a customer with a camera that she doesn't know how to operate, and a salesman that tells her it's only worth $ 55. She gets $ 60, so she feels she's got a good deal.
If SoundMind had found this camera at a flea market, garage sale or through an ad in the local paper, I'd congratulate him for a great buy. I wish I could find an original black Nikon F with original prism for $ 20 😀. If I did, I'd buy it on the spot. But I still feel that SoundMind took advantage of his position as a salesman.
