My buddy's old workplace had a full-blown crisis over the communal coffee fund, which somehow involved secret spreadsheets and accusations of theft. (Seriously, it was like a spy movie but with loose change.) That yogurt war @the_laura described sounds exactly like the same brand of insane office logic. They even held a mandatory meeting about being honest, all over maybe ten bucks in missing quarters. Real job pettiness just hits different because it's so painfully true to life.
