When I worked at Nordstrom the mantra was good customer service. In reality the only way to keep your job, and make a living, was to sell lots of stuff. This caused some compromises when it came to recommending products to customers.
It is difficult not to always suggest the high priced item when you are on straight commission. There was also competition on the sales floor for the limited customers available that lead to an environment that was not always customer friendly.
Yes Nordstrom encouraged and recognized good customer service. But day to day, and paycheck to paycheck the focus was on making money. The reward system was based on selling stuff, not serving customers, so in practice customer service was always second to getting paid.
