If you don't do anything it will keep going on...
There used to be a supervisor at one of my jobs that would throw his fruit peels in my trash can instead of his. It would stink up my cubicle...
Then when I transferred to another department and went to pick up my check the last day before Christmas break, there was some food left over in a conference room from the annual pot luck party... I found some left over shrimp and put one in his Kleenex box on his desk so it would stunk to high hell when he got back in January... Paybacks are a *****.... :icon_fU:
