I was able to read people's minds during my trip this week.

"While in this line, the person in front of me must want me to stand 0.2mm behind him. And if he inches forward in any way, even though the line isn't moving and I can clearly see the line isn't moving, I'm still going to, without delay, move right along with him to maintain that 0.2mm gap. There is no way that he's only moving forward just because he doesn't want me to close, because 0.2mm is the optimum. Now 0.1mm, that would be WAY to close."
