I ordered the Avocado margarita a couple of weeks ago and the bartender made it fresh, however he made an entire blender full. The next person that ordered it would have gotten the rest of what was in the pitcher. I'm guessing it just makes more sense this way, especially since he had to cut open an avocado and it's easier to put the whole thing in then instead of letting it brown waiting for the next person. And during F&W, it just makes more sense to make larger batches at once. Most people, including me, are not going to customize it.
