I'm not sure I even got the point, it was a long text and the author seemed to ponder aloud more than underline the root problem. But what I got was that she was overrun by the representatives because she didn't set boundaries and didn't refuse to accept their help. A simple "No thanks" would've gone a long way.

There's no point in blaming the representatives: they probably try any angle they can find to approach you unless you decline. Suppose you go to a bookstore and the clerk comes over, asking "Can I help you?" and then you answer "No, thanks. I'm just browsing." They don't know you if you're a good gamer or a newbie, so you just need to tell them yourself.
