Colleague buys 2 bananas every Monday. Has done so ever since I've worked there (1+ year). They sit on her desk until they go bad and then get thrown away on a Friday. EVERY week. I've never seen her eat one of the damn things yet come Monday another 2 take up residence on her desk.
Otherwise she's a lovely woman and a great pal. But those bananas... just looking at them makes me ragey.
Anyone else have totally petty, pointless things that you should ignore but instead feeds the inner rage demon?
