Exactly a year ago at Hermes San Diego...my plan was to just pick up two small items an SA had held for me since my local H did not have these items in stock. I had every intention for it to be a 10 minute trip as I had my DH with me. As I walked in, I noticed another SA working with a woman and he was bringing out two large boxes for her. My heart started palpating as I knew from the size and shape of the boxes that there had to be Birkins inside....
Sure enough, out of the first he pulled a gold 40cm Birkin with PHW...beautiful bag, but not a size I loved. Then he reached for the second box and starts pulling out another bag. As soon as I saw it, I let out an audible shriek, it was the bag on the top of my wish list - a 35cm White Birkin PHW. Both the SA and woman immediately turned around and stared at me and I explained to them how much I've been wanting this bag. The woman lets out a smile and says, "Don't worry dear, I don't plan on buying this bag so it's yours if you want it." And the rest is history!
So not exactly "on the shelf" but there when I walked in the store
