I went into Subway today just to get a drink. I asked for a medium (I admit I am in the habit of doing that everywhere, and it's usually a pretty safe option). She pointed to a giant 40oz Big Gulp-looking plastic cup. Apparently "medium" has been growing not just at coffeeshops.

The best part is that, as I slurp down my 600-calorie soda, I can read on the side of the cup about how many Subway sandwiches are so healthy and just 200-300 calories.
