"Can you make me dinner reservations?" would lead to a response like "Any preferences on the type of food and location?"

Over time they learn your preferences so they don't need to ask location for example next time.

Your right though people aren't likely asking such generic things in the first place, but rather something like "can you book me a great mexican place for dinner tonight, 2 people, has parking and casual attire somewhere with great yelp reviews"

Then they send you the best options they found (and the benefits of each one and price range) then you reply back option 1 and they book it.
