The Great Gatsby, tumultuous argument

Could you please tell me if the word "argument" in the chapter Seven of The Great Gatsby means just "conversation", "discussion" or rather "quarrel"?

The prolonged and tumultuous argument that ended by herding us into that room eludes me, though I have a sharp physical memory that, in the course of it, my underwear kept climbing like a damp snake around my legs and intermittent beads of sweat raced cool across my back. The notion originated with Daisy’s suggestion that we hire five bathrooms and take cold baths, and then assumed more tangible form as “a place to have a mint julep.” Each of us said over and over that it was a “crazy idea.”— we all talked at once to a baffled clerk and thought, or pretended to think, that we were being very funny....

Thank you.
