not if you post a message on forums (pick n apron bazaar) asking for a runner for iron, ppl will understand wat u need, at least for me, and the trade works perfectly, much faster than dropping the ores, even if he did press accept twice. i find this the best way to gain xp, you mine the ores till full inv, give it to the runner, and by the time he is back u will hav another full inv of iron. i usually do this in the two varrok mines tho.
