I'm a jargon enforcer when there is genuine ambiguity as to what exactly you are talking about.
Another sizing issue is that number of shots of espresso in a drink needs to be an entirely separate metric than the total amount of liquid. You should have to specify both for each order.
The other issue is that most coffee drinks totally stink and are pointless.
Another knock against the Adbusters crowd: You can talk smack about Starbucks or Barnes and Nobles, but my hometown in NJ and most places in flyover country, before beautiful capitalism, had no way at all to get their hands on snooty big city things like espresso and trade paperbacks. And no way to get sizzlin' fajitas before Chiles.
