Lab tidy

One of the labs I look after is always messy - unlabelled samples lying around, rubbish on the floor, syringe needles left on the bench... I've given up complaining about it, and this morning I thought I would have a tidy-up which involved disposing of a load of samples. Part of me hopes that I have chucked away something important, as it seems to be the only way to get the message across.
