Palfrey's life

I'm fairly sure this sort of problem isn't just me. Every so often I get a question in my head, and I can't stop thinking about it until I know the answer. Most of them simply involve a quick trip to Wikipedia (or Google), and then the problem is solved. However, in this case I don't think it'll help. Specifically, if you're going through the whole airline security crap, and they become *somehow* convinced that you've got a couple of kilos of purest china white shoved up your rectal cavity, and therefore need to have a more intimate look. What happens if during said procedure they believe that you're enjoying the process? Is there some sort of official guidelines? Some sort of upper limit of observed pleasure before other options are considered? Or is it just a matter of "don't ask, don't tell"? Could a drug smuggler theoretically know that they'd never search him/her in that way ever again because of enough earlier trips and a little mark on a official record saying "will enjoy this too much"?

This may be influenced by my being convinced that given I *always* get searched by the bastards in US airports, that it's only going to be a matter of time before I'm taken away into a private room and told to strip. I'm pretty sure that my responses won't be like the above, but it got me curious. My colleagues (whom I wouldn't mention the above scenario to) discussing the best ways to smuggle cocaine through an airport in the bar last Friday didn't help either....
