This is true, but I am comfortable with what I have said. This seems to be the culture of the store and they are ok with that. I'm just looking to expand my knowledge base and become a regular customer. I'm sure I will venture back soon enough as there are many things I want!
Did you ask for help? Did you tell the security guard that you'd like assistance and have him get someone for you? That's the fastest way to get the help you are looking for and all the security guys at this boutique are able to call an SA for you.
I see a lot from posters on this thread about how no one talked to them when they were in the store but why not just say to anyone you see "hi I'm looking for help" If the SA is not free, they'll certainly find someone or tell you how soon they can be with you. I personally like to browse and be left alone unless I have a specific question. With H, yes-you need assistance especially at the store you're talking about as there's not a lot of room on the floor for inventory but there's no harm in asking.
H sales associates spend most of their time communicating with their clients that are NOT in the store. That's how they sell things, they keep endless wish lists and try to match up product that comes in with those lists. I'm not saying it's ok to make a customer feel ignored but to assume that they're actively avoiding you seems overly sensitive. I shop at all the designer shops in that mall and service is spotty everywhere unless I communicate exactly how I want to be helped and if I don't need assistance I tell them so no one is wasting time.
I personally love the staff at this boutique and think that you need to try with the SA you were working with when they're back in the store on the regular schedule and tell him/her exactly what you want to learn about and what you're interested in. Weekdays are best, you can spend some time asking about the products you want to know about. If the SA is not due to come back to the store anytime soon, ask for the Asst Mgr or Mgr and ask them to chat with you which they would be happy to do. Another SA will likely not want to jump in though since it sounds like you already started a convo with the SA who's out sick or whatever. You can even call ahead and give them a time window that you'll be around which will likely result in a much nicer experience.
Anyway, that's just my two cents on this particular store.
