This made me think about something I saw that stuck with me. I was waiting to be seated at a restaurant when I noticed one of the hostesses, who was a young attractive girl was standing behind the hostess station talking with another hostess. Thing was, her right leg was wrapped around the leg of the stand and there was a protrusion from the table that was directly at her crotch level and she was moving, kind of bouncing into it. I don't think she realized what she was doing because she kept on talking to the other employee, but the protruding edge was right on the correct spot, so I chalked up the bouncing into it as nervous energy.
