Much more interesting is the link to their complete styleguide - http://www.starbucks.com/static/reference/styleguide/
Also interesting, but less technical, is the BBC's style guide: http://www.bbc.co.uk/gel
I'm a grammar nazi at heart methinks.
Good read though, although I think the BBC has started to make some serious mistakes and are getting a little too experimental. All the animations they keep doing everywhere are getting in the way of the actual reading and are very distracting. The home page is now looking a real mess. At least they've got rid of the annoying 'slide' effect their carousel had which meant if you moved your mouse around the whole page seemed to jerk around.
I too am a grammar Nazi, and the very first rule off grammar is that sentences, delimited by punctuation marks such as the point, have subject and verbs, unlike your four sentences above.
Or maybe it is because English is not my mothergrammar?
And, of course, 9/10 people who read that sentence (yes, a single sentence) knew exactly how the OP was intending it to sound in their head.
I guess what I'm saying is, you can be pedantic around here, but not to the level where it looks like intentional misinterpretation.
