Stereo Installation

I really wanted to keep my dollars from going to Best Buy for a stereo installation I was having done. I told Don that he could have my business if he could undercut them. After two phone conversations about my specific job I decided to let him do it. I really had a bad feeling about his attitude after our talks as he is technically professional, but very much on the short and rude side of that coin. On the day of, I bring him my car and my own purchased items, and he looks at me like he is clueless as to why I'm there. I also wanted to reverify that I would be able to make an appointment in 3.5 hours from now. He responded with a "ya I know, ya told me" as he walked away with his back to me. His shop was very uninviting with an awful stench and typical self owned business signs hanging saying, "this is not Burger King, you don't get it your way" and the like. With all of this I was a breath away from saying "this isn't going to work", and pulling the plug and taking my car elsewhere. All I was hoping was he didn't make me regret not leaving. I sat for 3.25 hours straight w/o a single word or update, with my next appointment approaching. He came out I paid and we spoke a minute, when I inquired about a specific detail of the job he of course spoke to me in a very condescending manner. All told the job was done perfectly to my estimation. However, I can't understand with the way small business owners are losing business to big box entities, that he wouldn't be bending over backwards to promote his establishment in a friendly manner. The other reports of his attitude are definitely true, and the final bill was the same as Best Buy, so I am just happy I got the job done first time. I would not return.
