You can just drop any drop-able item anywhere ... no one else will pick it up. So, maybe istead of in the chest, right next to it would be good.One time I dropped everythign everyone had or was wearing, in one spot. When I left the inventory screen and came back out to the game screen, I saw this huge, comglomeration of all the items, sitting and spinning in one spot 
It was a nightmare to pick them all back up, one by one ... so the lessen here, drop one thing anywhere you want, not too many in the same exact spot
