That's a accurate break down in a lot of ways about IG/club/bottle girls, of course there are always exceptions, depending on when and where and how you connected, but there is a lot of sense in that.
There's one who lightly declined when hit her up to meet me in LA at Motherwolf last summer (which is one of the more exclusive spots in the city) she's hot, but this was more to just to share the experience, to me, it's even like doing someone a favor, that you would even get an invite
however, if I had a table at the local San Diego spot, probably would have gotten a yes, ironically later, she was talking about it, as her girlfriend and her guy went to that spot, and I was like "I invited you and you passed!"
sometimes people don't share your value system, and just aren't where you are in life, and trying to put them up, doesn't even work, because it's not what they want, or where they feel comfortable.
