That's a good category. One time a guy stopped me on the sidewalk to ask for directions, while holding a smartphone in his hand. Fishy! But his phone was broken and he wanted directions to the Verizon store. Sometimes people are just crazy. I was walking to the Port Authority bus terminal in NYC one night around 2 a.m. and brushed shoulders with some guy. He dropped a plastic bag, then started complaining to me that he was a boxer and that was his chap stick or Vaseline or something he needed and now it was no good. I offered to buy him a replacement and we walked in to the station together. He was more intent on the mission than I was and he got a few steps ahead, allowing me to take a detour. I had to lie low by my gate until the bus showed up, but survived to tell the tale.
