I would just tell the player to make an unarmed attack roll, and see what happens. If the innkeep wants to fight back, then we roll initiative.I don't think it's confusion over the basic play loop (though I don't want to put words in other people's mouths).
Suppose I say 'I want to punch this innkeep in the face' (using my authority over my character).
The DM is expected to respond. Fine. Does this trigger an initiative roll? What if the DM says 'OK, you punch him in the face', and I say, 'no, I want to fight him, roll initiative.' Or vice versa. Who is in the right?
Obviously, it's not an insurmountable problem. It is an absence in the rules, though: as @hawkeyefan said, you're expected to insert your own expectation.
I wouldn't say this is a complete non-issue in actual play, by the way. For example: as DM, I've occasionally resolved fights without going to initiative, especially in a dungeon situation where there are lots of weak enemy groups, or in situations like duels or fistfights where it seemed more sensible to handle them narratively. Some of my players were surprised by this. If the rules had some simple guidelines as to when to roll, and when not to roll, this wouldn't be an issue. It might also help novice DMs who might not realise that not rolling initiative is even an option.
Now, if the innkeep was expecting a punch to the face, I might have everyone roll initiative right away. Ultimately, it's a DM call, not a player one, to roll initiative IMO.
