She sounds like a little bit of a jerk. Or maybe a big bit of one. I wouldn't go out of my way for a person like this. I vote for option 3.
It's not to your advantage to be unkind to her either. You may not make friends but at least she might become an acquaintance. And maybe she ain't so bad after all or maybe she is. But taking her to a reputable reseller is as nice as you can be.
Let her know you already mentioned it to the Hermes store and indicated an interest in X bag, but there're no guarantees. Or that the waiting list for that particular bag is closed. This way, you don't lose your mutual friends, and it won't be awkward if you two run into each other in the future or if she calls you incessantly.
You may not care for one more friend, but no one can afford one more enemy. Some people are simply dirty for many or no particular reason, I've learned my lessons.
Eric, If this woman is the "difficult" type do you want to present her to your store as a friend? If this person is not kind to you; she will not be an enhancement to your life. You can, and absolutely must choose your friends.
Out of the choices that you posted, I would be tempted to say that my quota was filled.
I would call my store and let them know that I am not really close to this person;should they use me as a reference.
I'm going to vote for option #1 as well... when it comes to H bags, it's every man and woman for themselves... (insert evil laugh here)...
Don't bring her to the H store, you never know what these sort of people will do to your cred.
i just thought of this....tell her the SAs have asked you to stop "helping out" your friends looking for birkins b/c they have other people waiting on their "lists."
