It seems to me that the poor service at so many of the Crappy Auto (Dis)Service centers, is a type of "Prisoner's Dilemma" situation (as in standard Game Theory).
When there is a limited but shared resource, it is in the common good of all those stakeholders to preserve the overall value of that resource, and thus their share of it. But if individuals are able to 'cash in' a part of that resource for their own immediate, short-term gain, it can be tempting for the individual to sell out, and leave their peers holding the bag.
(Common examples are plea bargains only offered to the first part to squeal on the others, or a tribe who has control of a valuable herd or other collective asset. So, too, with the reputation of the CT brand, especially when it comes to automotive service.)
The Crappy Dealers could all choose to work towards the common goal, of maintaining the brand and reputation of the Crappy Tire name, for their own common good.
But if 1 dealer (maybe a Moaner 1?) decides to exploit that reputation, by ripping people off, they can do so without significantly undermining the overall reputation of the brand as a whole. In effect, they are 'selling off' the overall Brand's reputation, for their own personal, short-term gain.
The people who stand the most to lose in the short term are their own peers, who might well have been protecting the brand, through fair dealings and competent service. As the reputation of the overall CT service drops in the public's eye, they would gradually lose customers and profit, as news of shoddy service spreads. The (hypothetical) 'good' dealers would be getting screwed over by the (very real) bad ones.
In fact, those dealers who choose to give up personal gains by being honest and responsible would in effect be subsidizing the bad ones.
At some point, even a (hypothetical) 'good' dealer would be tempted to start 'cashing in', and screw over customers, too, to get in on the action, and grab some of the benefits, before the reputation is destroyed entirely.
I will leave it up to the reader to decide for themselves where, exactly, the CT Brand currently sits in the downward spiral of suckiness in automotive service, and rate the Dealers they may have come in contact with.
But one thing is sure, based on the sheer number of complaints we see each time CT runs one of their "Free Tow" offers:
Thie downward spiral continues at the Red Triangle of Crap (Dis)Service Centers.
