I'm not sure what this has to do with the original scenario, where the two people are still trying to assess each other. Or what status has to do with those examples.
Ah, the confusing world of NT social games...
Basically, imagine each person P has a number X, called their "statusvalue", and the way we respond to others is a function of the statusvalue difference between us and the person we respond to. Suppose that your number is, say, 5, and the person you are approaching is single, sought-after and attractive, and therefore has a statusvalue of 8. Therefore your body's automatic response will be a "+3" type response, i.e. you will defer to the person you are talking to, attempt to please them, etc.
In order to work out the correct response, you need to think what your response would be if the person asking you for the drink were a 2 on the statusvalue scale. This will be a "-3" type response, i.e. you will assert your desires over theirs, and interpret their behavior in terms of whether it meets your expectations. Then, you gradually condition yourself to always give "-3" type responses, i.e. give off signals that you are three statusvalue points above everyone.

I completely understand the general idea here, I just think the drink-buying thing is a bad example. In my experience, refusal to buy a drink for someone who's flirting with you doesn't send the signal "you're X statusvalue lower than me", it sends the signal "I'm not interested in playing this game at all"
Followup to: Do you have High-Functioning Asperger's Syndrome?
LW reader Madbadger uses the metaphor of a GPU and a CPU in a desktop system to think about people with Asperger's Syndrome: general intelligence is like a CPU, being universal but only mediocre at any particular task, whereas the "social coprocessor" brainware in a Neurotypical brain is like a GPU: highly specialized but great at what it does. Neurotypical people are like computers with measly Pentium IV processors, but expensive Radeon HD 4890 GPUs. A High-functioning AS person is an Intel Core i7 Extreme Edition - with on-board graphics!
This analogy also covers the spectrum view of social/empathic abilities, you can think about having a weaker social coprocessor than average if you have some of the tendencies of AS but not others. You can even think of your score on the AQ Test as being like the Tom's Hardware Rating of your Coprocessor. (Lower numbers are better!).
If you lack that powerful social coprocessor, what can you do? Well, you'll have to run your social interactions "in software", i.e. explicitly reason through the complex human social game that most people play without ever really understanding. There are several tricks that a High-functioning AS person can use in this situation:
