Interesting reading the reviews of this Tiffany & Co location...
I have been to this location a few times to buy gifts, have jewelry cleaned and just to browse. I have always experienced great customer service even when I clearly wasn't buying anything. Yes Tiffany & Co is expensive, but it also comes with piece of mind about your purchase.
I even showed up after hours one evening to find they had just closed. Their head of security was willing to drop my cuff links off so I wouldn't have to drive back to drop them off and then a third time to pick them up.
