Am I in the wrong here?

No, but they leave their door wide open so the smell of food drifts into my home.
So I went to complain, but both the studio owner and the person involved
asked me what the problem was. I tried to argue my point, but our voices just started getting louder,
so I just ended up backing down.
Now they say they're going to keep leaving the door open to ventilate the place.
Sigh... it's so frustrating, even though it's not a huge deal.
