This doesn't bother me as much as the movie-popcorn pricing system, which seems to be rapidly spreading to everything (Cold Stone and Jamba Juice are two particularly egregious offenders). You can have the miniscule size for $5, the "medium" size for $5.75, or the insanely large size for $6.95. Of course they never even expected to sell the other two sizes, they're only there to make the medium size (which is still way more than I wanted to eat) look cheap.

While I'm on the subject, here's a fun fact: a chocolate-peanut-butter flavoured milkshake from Cold Stone, in their largest size, contains over two thousand calories.
