Duncan - I am catching up with threads and ran across this. This is awful. I too have had varied experiences with Hermes SAs.
I don't think Hermes exercises as much quality control in their SAs as they do their product. I have to say though, most of the SAs that I or my DH have encountered have been fairly nice and patient. Sorry this happened to you. You might want to purchase your scarf from another SA.
At an H store last week, an SA told me not one, but two outright lies. (Note: Anyone who read my post on the bolide, or the updates on this store can put two and two together to figure out which store this is. But the SA referred to here has not been mentioned in any of those posts - only nice SAs were mentioned.

)
On the first day of my vacation, SA1 showed me a black bolide w/silver hw, which I loved. I wasn't ready to buy it then, so she told me she would be off the next day but back the day after, (Day 3). On day 2 I went in to look at scarves; SA2 said SA1 would be back tomorrow but showed me some scarves. I picked out one, and was going to buy from SA2 and thought it would be nice with the bolide. Then SA2 offered to show me the bolide again, but when she brought it out, it was black w/ gold hw. When I asked, she said (lie 1) they did not have a black w/ silver hw - so I thought maybe I mis-remembered the color. Then she told me (lie 2) that SA1 would not be back for several days (in direct opposition to what she said earlier). She then tried to pressure me into buying that bolide that evening, saying it might not be there when I come back, since it was the most popular color, size etc., etc. and that SA1 would get credit for the sale. But I did not want black w/ gold hw, and I was concerned about her change of story on SA1, so I left without buying the bolide or the scarf. On Day 3, I went in to see if SA1 had returned. She
was there, and showed me the original
black bolide w/ silver hw, which I then purchased. I thought about reporting SA2 to the store manager, but gave here the benefit of doubt, plus she did show me a lot of scarves. But it threw a pall on my first purse purchase; if I had listened to her I would have ended up with
no bolide.
Sorry to hijack your thread with my story - but it just goes to show there can always be a bad orange in the bunch!
