Interesting perhaps because here (on a forum) ... you can be anyone you want. Personally ... I'm me, myself, just I. What I type is what you get in the real world ... with marginally less swearing ... and zero noise. Lucky you people!
If I feel the need to "bag a product or manufacturer" it's because I'm unhappy with their service, their product or how they treated me when I complained to them, and whether they assisted me to fix the issue that their product or service has caused, or explained to me why/how they can or can not help. You don't pass that test, then I'm gonna bag you firstly to yourself, then everywhere, not just here on some forum.
EG: I've had a little trouble with two retailers recently. Nothing overly earthshattering, just annoying at the time. Both companies have surpassed my expectations, once I got to speak with "the right person" to explain my dissatisfaction ... but it's usually not the first or second person who might help me, which is disappointing, but something I expected.
I think it takes a lot of non-genuine staff (who work for the money) to get to the one very genuine person (who loves what they do and love that they also get paid to do it) who says "Oh I'm so sorry, what can I do to help OR here's what I can do to help". You just have to get passed the less helpful people first, and this is where most customers lose faith in the company ... especially after the product has failed.
However, as customers, I think our attitude also has something to do with how we get treated after the product fails. If we go in snorting steam, cussing, and red faced with our frustration (yes it can be frustrating) without finding the right person to talk to ... we often find no satisfaction ... and many are too willing to throw their hands in the air and then run down a company ... before really giving them a chance to correct the issue. Remember that those people behind the counter or on the phone are people as well, with biases and feelings just like us, the unhappy customer. Rather than yelling "I have this problem with your &*#@&%^& what are you going to do?" ... you could try a calm "I've got a problem, who can I talk to about it?" ... you'll always get better results.
In saying that, there are some companies, staff, people, who just couldn't give a rats festered behind and deserve the bashing they get, be it on forums or otherwise. I can name two (well known often advertised) companies who get that ranking from me, but I'd rather save my breath and just simply not deal with or think about them ever again ... and I've told them so.
