I have shamelessly stolen this from the good guys at Jalopnik (FTW!) but when reading this I noticed it does not just apply to cars/mechanics......this is a fundamental problem with everything including business operations. We have all turned into a bunch of bean counting idiots. We have failed to recognize that we are only hurting ourselves when we squeeze the bottom dollar out of our relationships.
We should be building proper relationships with these people, and paying them for their worth. We need to change attitudes from "Saving money" to "Making sure money is well spent". The big players in the industry that continue to burn bridges (Wallmart, G.E., Apple, Dell etc) are starting to feel the burn of this as their suppliers/subcontractors and staff suddenly throw a spanner in the works, jamming up the whole system, and costing the firm in more than just capital.
Anywho, have a read, and have a reflection.
