I'm an upset customer and I was mean to them. Ok, so I wasn't exactly nice to them and pointed out their poor customer service. So instead of sending back a professional response, insult a customer who paid for something and did not get it.
I worked retail for 8 years. Circuit City, I started out as a sales person, sales manager, corp. sales trainer, store manager. In all four of those capacities I dealt with upset customers, had I ever repeated one word that a customer used towards me, back to that customer I would have been fired on the spot.
That's the difference between a "piss poor" business and a professional business. I think I'll stick with Ames Perf., NPD, Ecklers etc.
