This seems like a good opportunity to point out to those having to use syringes on a plane to please not just throw them into the trash. Before you do so, please ensure that the tip is covered.
I recently had a passenger ram one up their hand whilst trying to recover her watch which had fallen into the trash bin.
Also, if any of your personal posessions fall into the trash, please contact one of us crew, as we can pull out the trash bin and also provide you with gloves.
