As a Member Of the Trade cable-maker it's an unfortunate by-product when difficult clients enter your realm. Heads-up; this is a bit of a whinge n whine. Continue at your own discretion lol. I had a potential client message me via one of my selling platforms recently, asking if I can help him with a 'cabling issue' he was having (hum through speakers). I advised him politely that I just make and supply cables conformant to what I advertise and that there would be no guarantee that supplying him a set of my cables would necessarily solve his particular issue. Some of my cables are designed and advertised as having multi-faceted EMI/RFI shielding of course, but his particular issue sounded pretty severe, maybe ground-loop or such. It got to the stage where I ended up asking for his number to call him to get a clearer idea of his issue and requirements as messaging back and forth takes a lot of my time and he didn't seem to know how to express a clear description. He explained the issue during a call and I subsequently asked him to take photos of his existing cables, cable-spec, connectors and equipment sockets. I could then go further and propose at least a matching set of cables conformant to what I already supply as standard. Turns out he needed a set of handed 4 pole XLR cables with power and signal capability for some obscure and obsolete Infinity amp/speaker combo with 'servo control'. I politely advised him that I would not be able to make him the cables as I would not be 100% confident that I could match the technical and safety requirements of such a cable. I've never heard of 4 pole XLR connectors being classified for power connections let alone signal AND power, have you? In closing I suggested he explore if there was a 3rd party manufacturer that could supply him with such cables and bid him good luck. At this point he became offensive and abusive, replying that my refusal and explanation were 'nonsense' and 'anyone can make such a cable'. Without giving a reply I decided to block his messages. I cut the cord immediately when people become arrogant or offensive. He subsequently started messaging me via another advertisement on the same platform with even more abusive and offensive language. I then reported him to the platform for intimidating/offensive behaviour. So, in the blink of an eye the communications turned from cordial and exploratory to outright offensiveness on his part simply because I politely refused to assist him with making a set of cables after giving him a justifiable and reasonable explanation. What he probably failed to realise is that if I had used incorrect specification (for voltage) cable then depending on the severity of the spec deviation would lead to at best, damage to his equipment, at worst his house going up in flames. Who do you think would be held liable? I doubt my own insurance company would look favourably on me in the instance of a claim. I'm all for helping clients to find solutions for their cable-requirements as it can be a really interesting and rewarding process. But I absolutely reserve the right to refuse service/supply when I consider the requirements go too far outside my own confidence and knowledge levels - especially if I think a request has the risk to become a potentially dangerous situation. Some people have absolutely no idea about what's technically possible and not possible, safe or unsafe sometimes, but the sheer entitlement and expectation that you're there to supply cables at their whim, without regard to technical feasibility or safety is just staggering! Sadly, I have experienced this here on SBAF recently too. A member some months ago asked if I could supply a headphone cable to his own exacting specification and I politely refused, citing that I did not have the type of cable he wanted and was not willing to go outside my regular supply chain/environment just to satisfy his demands. He recently started messaging me again here (to the point of badgering me constantly) and when I refused his request and subsequently decided to block him he bacame offensive by leaving a salty message on my profile page. I reported his post as offensive and blocked him, so fortunately I don't see his posts or messages anymore but other members will probably be able to see his post. Not wanting to defame other friendly members who have commented nicely/friendly on my profile page I will just say this particular member's name begins with T. What to do? Am I being reasonable and professional when refusing individual requests, or am I just being a cranky old fkr? I'd like to think I'm acting responsibly but it's a difficult balancing act sometimes. Most folks are nice and really happy/satisfied with the end-product usually. 500 units sold since I started operating commercially sort of verifies that. But it's the one or two individuals that come along and sour the experience sometimes. Well, it's Friday and beer-night starts in approximately 3 and 3 quarter hours (6pm kickoff lol). Time to switch off the soldering iron, rest my fingers and crack open a couple of Duvels.... Cheers! Feel free to comment. Either way is fine and if the SBAF member I cited decides to chime in here please remind him I won't be able to see his messages. I don't particularly care to engage him in more pointless conversation but I can imagine he'd want to defend his position/ego. lol Anyway.... beer-run!
