Femina you seem to be a wonderful and understanding person! I do feel everyone should be treated equally as well. That is how Hermes was sold to me long ago. The idea that you will receive endless assistance and it would be on a one to one basis.
As for tipping, I do not think you should tip. I feel Hermes should take care of their employees in that respect. I do feel like small little token items are perfect. Like a thank you that Noriko sent to her SA. OR, if you know your SA loves a certain chocolate or soap and you pass the shop where you can purchase them...pick up a tiny box and drop it by for no reason. It is the thought and not the amount. Everyone loves to be thought of and made to feel special.
As for the ulterior motive...I do feel if done a certain way it will look like your buying them. To me, that is no different than going in Hermes and buying many small things when they know you want that Birkin point blank.
I had a friend that worked at Hermes long ago and she tells me it was obvious when people have a plan to purchase small items and then work it to go in for the kill to get their "it bag". The SA's see through it, but they keep face because that is their job. My girlfriend told me when you work at Hermes there is a small level of people who really spend money there repeatedly and then there are the people who are "trying to acquire" as she would say. The SA's all know what's going on and who the real customers are no matter what anyone says. Hey, it is a business...
That is why I asked a while back in a thread if you all felt being honest with an SA is a better approach than shopping for all the little items etc. and building a relationship if possible. I partly asked to hear what you all thought because of what my old friend told me.
