Interesting point, Newforest2, but I can't say that it has. The most intensive questioning I ever had was coming back from a long weekend in Geneva (late 80s) with a girlfriend. We got stopped and when my passport revealed it was my birthday that weekend, he was convinced that we MUST have bought an EXPENSIVE watch that we were concealing. Naturally he did not believe me when I showed him the 20 year old watch that I had on - further proof that I MUST have bought a new one. I'm sure that many do conceal new watches.
Other than that, I can't think of more than one other peremptory 'stop'. So perhaps I just have the natural face of the genuine innocent ...
