When I could finally afford my own computer in 2000, I decided to take a look at Macs. I grew up on Commodore 64/128, and we finally got a PC when I was about 14. I knew NOTHING about Macs. I went into Best Buy and looked around but found no Macs. I found a salesman and asked about the Macs. He gave me a little chuckle, rolled his eyes, and said "We haven't sold that crap in over five years." Now, correct me if I'm wrong, but the iMac came out in 1998. Best Buy sold iMacs at one time. So, even if they only sold them for one day, it couldn't have been more than 2.5 years since they quit carrying Macs. He acted like I should have already known that they didn't carry them. And, you don't roll your eyes and laugh at a customer, and you don't tell them that the product that they have chosen is crap. If you don't sell that product, you lie your ass off and try and convince them that your product is better. i.e. "Yes, the iMac is a very good computer, but I think you will find that this computer is better because of a, b, & c." To laugh and call it crap is in my opinion an insult to my intelligence. And I don't have much of that to insult!
I hate the whole extended warranty battle as well. I recently began upgrading my kitchen. After researching products and prices, I chose Frigidaire stainless steel appliances and found the prices I wanted at H.H. Gregg. My first time ever in H.H. Gregg, a salesman found me and helped me find the dishwasher that I had chosen. When the transaction began, he started trying to sell me the warranty. I told him "I will absolutely not purchase a warranty. If you bug me about it, I'll leave here with my dishwasher, no warranty, and never return. If you don't say another word about the warranty, I will find you personally to make each purchase as I upgrade my kitchen over the next year or so." I have since also purchased a microwave from him, with no mention of an extended warranty. I plan to get my stove next month, and I intend to find the same salesman.
