I too think it is harmless to take a wrapped piece of cake or a tub of yoghurt or an open bottle of water. The are only going to be thrown out! But, yes, still be prepared to be reprimanded if caught. One of those things though. You can't have a rule for some items and not for others. ie. It's OK to take a piece of cake but not a cutlery set.
I once saw a girl take about 25 cereal packets home with her. Although I would never 'dob' someone in I sure hoped that someone else would catch her.... There's a line that I think she crossed!
