Pg - I did just that once. I refused to clean up after them. Well it got to me and after weeks gave in. I found so many, what I call "science projects" in the frig - takeout food unrecognizable, etc. I keep thinking would they live like this at home & thought no - oh, but wait - they have a wife to take care of this stuff!!
When I was on strike I went into our supply room & there was sh*t all over the place, doors open, drawers open - pigsty. It took me literally hours to clean, organize it. After that I said I'll keep the supplies up but if you guys choose to have it as a pigsty - go with god, that's your decision. Amazingly that they are being good about - it's the kitchenette they avoid.
