I agree, sometimes its not what you say, but how you say it or the tone that is used. Sadly it sounds like you had a poor excuse for a sales associate helping you, but I've learned all companies have a few bad employees in the bunch.
When a store is empty and they don't offer to help you, well there simply is no excuse for that. We were in Las Vegas and my wife wanted an LV handbag she had seen that was up on a tall display, and although the store was completely empty, the sale's associates couldn't be bothered helping us. They continued to chat among themselves. We were on vacation, and not dressed up, but I was wearing a Rolex, a golf shirt & jeans and my wife had on a Cartier watch and an Hermes handbag. After walking around the store for a few minutes and then waiting a few more, I said loudly enough for them to hear, "Let's go, we can buy it at the local boutique at home." We walked out, and a week later bought the same bag from our local boutique , and we never buy anything or shop at the Vegas location...so in the end its their loss.
You have a great bracelet! Enjoy it, and don't worry about the jerk you had for a sales associate. She isn't going to get any of your future business, someone else will and that's real pay back!
