That's super sweet that your VCA SA in LV sent you gifts. I love SAs like that and I'm sure she would appreciate it if you continued to shop with her. That being said, I think it would be a little rude to look and try things on in your local store and then not buy it, especially if a local SA was helping you to try things on. If she was putting the time and effort in, she should get the sale. You could always get your LV SA to send you the things you want to try, and then if you don't like it, I'm sure she would understand if you sent things back.
In response to your question, I agree with the others that VCA SAs don't make you play any games. If you want something, they'll do their best to get it for you. I enjoy this part of shopping with jewelry brands over bag brands, because even with other bag brands like LV and Chanel, you have to play games with the SA in order for them to sell you something that's higher in demand. There isn't a fair waiting list where I am and some things are impossible to get if you are not a VIP.
That being said, if you like the gifting, not all SAs will gift. Some are better than others, so if you find an SA who is good at gifting then I suggest staying with them.
