I worked at Sam's Club for almost 7 years right out of high school, through college and then a few years after, and I can say I learned a lot on how and how not to run a business, and especially how to deal with customers and employees. I worked under dozens of different managers and I soaked up everything I could about the business and especially the employee/employer relationship. I can't say I have any real negative things to say about the company, but I do know a lot about why they have done things the way they do, even though I did disagree with many company decisions and directions we had over the years.
