This is what I mean by status theories can explain anything: if buying the drink for the girl on average results in a good outcome, you could say that buying a drink on average raises your status in her point of view. If not buying the drink for the girl on average results in a good outcome, you could say that not buying a drink on average raises your status in her point of view. In either case, you assume rather than establish that higher status corresponds to the more successful outcome.
How do you know if "status" is a real thing if you can't measure it directly but only infer it from successful outcomes? The problem is that maybe higher status is redefined in each case as getting the good outcome, in which case "status" is just the property-of-resulting-in-successful-outcomes. Even if status is some external objective thing, if we don't know how to objectively measure whether it has increased or not, this is missing in theories based on predicting what happens if it's increased or not.
Later edit: I thought about it a little longer and my true argument isn't that good outcomes aren't correlated with higher status, I suspect they are. It's that the theory is missing where you predict which things will raise status and which will lower status. If not buying the drink helps, you deduce that this raised your status. But why should it have been raised? This last part is just filling in the blanks.

Status is not just defined and determined by good outcomes; the drink example is one small piece of a larger puzzle.

You could consider status to be rather like the magnetic field -- ...
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:
