Even if the dive shop followed my opinion on what the "professional" course of action and did a supurb job while finishing the class they did not want to teach, when they denied future products/services, then most likely there would still be complaints and people would still be incredulous that the dive shop had the audacity to turn away a customer for buying online and still be getting blasted like this one is now. For the message board active diving public, in the court of mob mentality, I guess there is no good way of getting rid of a disliked/bad/problem customer. Not saying that the original poster is a bad or problem customer, but apparently he had become a disliked customer.
Court of "mob mentality"?
C'mon.
People don't have a right to an opinion all their own, without the censorship of someone standing over them, telling them what to think and do? What's that about?
I have always found it amusing when merchants try to claim the right to impose a "cone of silence" around their activities and outright acts. Of course this is only claimed when they're engaged in something that others might find unseemly or worse! Never is an act of charity undertaken quietly, or some "good work" done without mention - or outright abuse in advertising.
I have sat on both sides of this table. As a merchant in the Internet space, I took
many unpopular views, most of them related to family and children in one way or another (e.g. banning the online newsgroups containing kiddie porn and such from my ISP, going after spammers, etc.) Most of what others have cited as evidence of me being a "madman" is a small, vocal group of people raising he-double-matchsticks about my stand on issues that they saw the other way on - no big surprise there.
There is no right when offering a good or service to the public to keep your actions private. You give up that right to privacy as soon as you hang out a shingle and start interacting with other people under the banner of commerce. Your actions become fair game for public discussion - because your actions are
inherently no longer private.
Nobody who does business with you has an obligation to keep quiet about their experience absent an
explicit agreement of confidence - such a thing is simply never implied, and in fact, I would argue that the public interest is served by public reports from those who you have dealt with in the past.
