The team I work with shares a floor with two other teams. Our team and the other large team tend to always have cakes, cookies and chocolates lurking about that people have brought in, but we only eat the food provided by our team. The third team never have any food. But, one of the people in their team is always taking ours, without asking. Today, a colleague had brought in some chocolate from vacation and put it out. The guy from the third team walked up, opened it and took some (not asking, not waying thank you).
