Dear Economist: What’s your approach to picking toilet stalls?

When I travel I am faced with a difficult choice: which of the toilet booths to use in offices or hotels. I always try to guess which one is the least used. Probability theory should tell me that all the booths should be equally used, but perhaps human psychology plays a part in this. My boyfriend believes the last one is the least used – contrarily, I believe the opposite. Perhaps this proves that, on average, all are equally used. Which one do you use?
