Well, at least you give credible customer feedback about your shopping experience to us - have you ever said as much to the manager of your local Wal-Mart? The aisles at our local Wal-Mart are plenty wide.
Yes...actually I have. I write letters and emails to any company that I'm not happy with and to companies that I get good service from.
I'm a firm believer that companies deserve that. Because of the fact that I worked in a customer service based job for a lot of years and I know how important it is to get feedback from people--good OR bad. And I try to be constructive about it...not complainy.
