I hardly ever dress up. I usually just go out in a t-shirt, jeans, and flip-flops. I don't really wear much jewelry either, but I always have on my great-grandmother's diamond ring and two silver bangles. Sometimes I'll have some studs in my ears. The service really depends.
I went to Hermes today, and at first the lady was so uninterested, but since I could only exchange and not return, I think that was the reason. But regardless, I just kept asking her questions about this and that, told her I liked her style, etc. She was still reluctant after a while, but she was polite. Towards the end though, we became friends and I think her prior attitude is really how she is as a person because even when she was being helpful, she still gave off a snotty vibe.
Then I went to Boodles, where I had the BEST service. I love that store. I knew what I wanted, but also wanted to look at other stuff (that I couldn't afford haha!) and the lady just brought out one after the other for me to see. And I had her give me so many prices too! I really wanted a ring or a pair of earrings to go with my pendant, and she offered to ask the designer to do a special order for me, and gave me quotes. Very helpful! I love the service.
At Asprey, I got wonderful service too and had a fun chat with the SA. He didn't look down at me at all, even though one of the other customers did because I obviously didn't look old enough to afford anything! But he was very patient and kind.
Nice customer service really makes a BIG difference.
