My employers bought us one of those huge American fridges. It was supposed to contain the milk for our tea and coffee and small lunches - ie sandwich / soup, etc.
We have several twats colleagues who on a Monday put a weeks worth of lunches in there, one person who buys stinky cheese so when you open the fridge it smells like a vomit fart, one person who after a catered working lunch puts all the left overs on a plate for her own person use (and forgets them for a few days but woe betide if they get thrown out) and several others who put stuff in the fridge that shouldn't be in there, I'm talking un-opened tinned goods, eggs! massive bags of dried pasta, porridge oats, honey, mustard. We have two long walls which have base and wall mounted cupboards which are 90% empty.
Shared fridges bring out the worst in people. AND my work kitchen has CCTV!
