The Great Gatsby, an argument broke out

I'd like to know if "argument" in this extract from the chapter Nine of The Great Gatsby means "quarrel" or "discussion":

The morning of the funeral I went up to New York to see Meyer Wolfshiem; I couldn't seem to reach him any other way. The door that I pushed open on the advice of an elevator boy was marked "The Swastika Holding Company" and at first there didn't seem to be anyone inside. But when I'd shouted "hello" several times in vain an argument broke out behind a partition and presently a lovely Jewess appeared at an interior door and scrutinized me with black hostile eyes.

Thank you.
