Body language can convey a lot. When I was a student I had a weekend job as a doorman at a tourist attraction, clipping tickets and telling people where to go, I was often put in the position of being asked to keep tickets for so-and-so who was parking the car and watch out for him. It got to the point where I could identify someone put in this position (even in a crowd)from about 100m away, and often surprised them by calling out their name as soon as they were within earshot.
