Nervous about Buying in Store

I am getting ready to buy my first ever LV bag in a few weeks, and am frankly nervous about going to the store and being treated like crap. Although I'm completely prepared to drop $6,000-$7,000 on a handbag, I worry that they'll see my lack of existing designer goods (TUMI is my fanciest item right now) and be horrible to me. I'm fully capable of walking out and I will, but does anyone have any tips? I'll be going to Mall at Milenia in Orlando FL if that helps. Thanks!
