ask what his endgame is with this order, and offer to cut to the chase

You know that's not going to work. He's not even going to understand what you mean by "endgame". He summoned you to do a specific thing, and that's what he's going to ask for; the idea of skipping steps just isn't going to make sense to him, because to him every step is as important as every other.

never let him finish a sentence

always be feeding him

So you're just going to have to stop him from making an order instead. Now, you can't actually harm him while inside the circle... but you can conjure food in his mouth, as long as he's not severely allergic.

So every time he starts talking, you just snap your fingers and a burrito forms in his mouth and he gets distracted by it. This should buy you some time; unfortunately, since there's not much you can do other than summoning food in his face, you're pretty much just left hoping a convenient coincidence gets you out of this mess.

You are now the individual who will be delivering said convenient coincidence. Who are you and what, exactly, are you doing?
