Oleg interview up

How many times have any of you answered the door with a tracking dot stuck on your forehead? I had an half hour conversation with 2 Jehovah's Witness's with that dot stuck on me head. I then upgraded to a vector pro clip for my hat but forgot it was on my head and only remembered whilst queuing in the super market, i was wondering why i was getting some sideways glances!! Thankfully I now use the Pro clip.
