When I was in San Francisco, I had a craving for the first time in I don't know how long. I had just eaten lunch at a cafe and stood to grab my purse and leave, when I noticed that I was craving a cigarette. It was sort of a sneaky crave, because it was so low level at first that I was operating on automatic. I looked around briefly like I was looking for something, and then realized that something was a store. I did put it out of my mind quickly once I realized what was going on on. But it was still a little eerie.
