I worked at the FE College and some of my lectures were at an annexe a few miles away from main campus. I had a desk there but I wasn't there every day.
I went in after several days away and the other ladies who worked there all the time were looking very green round the gills. There was a very bad smell in the staff room.
Said smell increased over the weeks.
End of term we were clearing out as we were to be moved onto main campus next term.
Blokes came and heaved out my old wooden desk. The drawer fell out.
My prawn sandwich, black with green powder on it, aged approx. 8 weeks, plunged to the ground.
What is worse, this was the second time I had left a prawn sandwich in a desk and forgotten........
