I just happened to glance into a colleague's locker as I walked by and noticed something strange.
SK: "Is that a banana?"
SK: "Did you mean to leave it in there?"
C: "I'll eat it tomorrow."
SK: "What if something happens or you fall ill?"
C: "It's not locked."
SK: "And in the meantime we'll be wondering where that horrible smell is coming from. No thank you. Please take it with you or throw it away."
