Ok, I can explain the Starbucks issue. The original sizes were Short (10 oz.), Tall (12 oz.), and Grande (16 oz.). Customers complained that the Grande was not large enough, so Starbucks added the Venti (20 oz.--'venti' means 'twenty' in Italian), and people eventually stopped ordering the Short size, so they removed it from the menu. Whether the fault lies with Starbucks for insisting on cutesy/pretentious names for its sizes or with American gluttony, I leave to you. I think it's somewhere in between.
Oh, and some annoying grammar/spelling issues: alright and alot when it ought to be all right and a lot. Similarly, every day and everyday, although the difference there is that both are valid but have different meanings. If something occurs every day, it is an everyday occurrence.
THANK YOU! for both the Starbucks explanation--I always ignore their silliness and simply say "small, medium, or large" and let them translate my order--and for once again reminding the grammatically illiterate of the correct forms of "a lot", "all right", and "every day" or "everyday". You made my day.
(Sorry, if that's an annoying saying too.)
