I find the "I'm not happy so I'm not paying" attitude to be utterly offensive. Sometimes, it seems that some folks assume, or insist, that everything on the face of the Earth must be "satisfaction guaranteed", instead of applying what is the
actual standard that applies when there
isn't an
explicit satisfaction guarantee: conscientious and professional performance of the service contracted-for, in accordance with generally-accepted standards.
I had some arguements with the owner, but he really didn't have a leg to stand on
Presumably because they promised to fix the problem, rather than just promising to do plumbing work for you. Satisfaction guarantees differentiate premium suppliers from the rest. They assume more of the risk, that the problem you have is bigger than expected (and of course that risk is even larger when all they have to go on, to give you a promise, is your word about what's wrong, the word of a lay-person rather than a recognized professional in the discipline, as was the case in the OP). However, consumers pay a premium when the supplier takes that risk onto themselves. Consumers pay more for the service, itself, to gain that assurance, to compensate the supplier for the cases when the job is bigger than what was implied by the quotation, which was based on a very early guess about what could be wrong. For some things, the low-cost providers - the ones that don't provide such assurance - can't even stay in business, because enough people are willing to pay the price for, and insist on, that assurance. By the same token, for some things, consumers are maniacally fixated on the price tag, and in those cases it is the premium suppliers who are unable to stay in business.
It took the plumber 3 hours to figure out he didn't have the right equipment to clean out a standard 2" pipe?
That's probably not what happened. Rather, what probably happened is that it took the plumber 3 hours to discover what the problem actually was, and two or three seconds to figure out that he didn't have the right equipment to fix it.
I'd like to know what town does someone leave a stranger unsupervised in their house and goes off to work?
I don't think it is worthwhile questioning the rationality of
either the plumber or the homeowner. Almost surely, they both did what was proper, and all the criticisms of them are without foundation. The most likely scenario is that it's just a bad situation, without any need to lynch anyone.
