I recently went into one of those chain coffee houses. I was mis-directed, I needed a new light-bulb and was helpfully directed to the nearest super-coffee-house. Indeed they do sell light bulbs (I thought only that only the burger bars sold them). It set me thinking about these coffee houses and why it is that they increase their repertoire of drinks.
Well, I believe I have discovered the reason: it is a well known fact that life is quantised and, everything has an infinity of possibilities until after the event (in which case it was obvious that it would be that and why would we think any different). Taking the quantum doctrine the coffee houses have determined that by offering a huge range of drinks (many unnatural) there is the remote possibility that one or two of them may turn out to be coffee.
Based on this finding it should be easy for you to get the best coffee by following this simple procedure:
1) Wait until the number of drinks reaches no less than 5**e.
2) Wait until the queue length approaches infinity (a good approximation is roughly 15 persons).
3) When making your order change your drink choice no less than 5 times and no more than 12 times.
4) Misspell your name by using all the characters of the previous person in the queue.
This recipe has been tested in 12 independent countries with statistically conclusive results (although your mileage may randomly vary since this is quantum).
