Hey there,
I would have to say the easiest way to open in this situation, is extremely early. The later the act the more difficult it will be, especially for someone who has problem with openers. As soon as you see her sit down, or as soon as you sit down, turn to her, really friendly and say 'Hi there I'm 'bob' nice to meet you' *big confident smile*. This makes everything so much easier, you don't need to sit there nervously cooking over how to open.
As you are going to be sitting next to her for the next hour or so, it makes perfect sense for you to say hello to her.... no pressure. I think this is a golden opportunity to build contact with your target, so simple and easy! *note to self, must go to university*
Hope this helps you dude,
Note: first post, about to write an introduction, just couldn't resist answering this :p
