In June 2005 a man wearing a white short-sleeved shirt, white knee-length shorts and no shoes passed through the security gates at Terminal 2, Heathrow Airport.
The security guards didn’t like him: he had no shoes, so they could not order him to take them off. He had no bag, so they could not search it. He did not set of the metal detector as he had no coins, keys or belt.
In fact, all he did have was a passport and boarding pass in the breast pocket of his shirt. It was a busy day, so they let him through.
The men monitoring the security cameras didn’t like him either. He stuck out like a clean patch on a soiled tea-towel, so they followed him with their cameras and they were surprised at what they saw.
The man, smiling faintly, walked every aisle of every shop, yet never touched or picked up any item.
He stood in every que at every coffee shop and fast food concession, yet every time he got to the front he just walked calmly on.
After he had done all this, he left the airport and was not seen again.
He was the worlds first airport tourist.
