My own strategy, such as it was, was to put on an official looking badge, hold a dairy and some papers in one hand, don a serious demeanor and pretend as though I would, at any moment now, be purchasing several missile systems and a Eurofighter 'Typhoon'.
It worked well, with hosts explaining their wares in intelligent and clear explanations. This usually led to an invitation to leave a business card (I had none) and in some stalls, oddly, an offering of candy from a bowl. Perhaps this was some arcane defense tradition I was unaware off. I happily took them none-the-less.
The odd highlight of the day was at an 'exclusive' stall that was selling private jets.
Now I don't want to accuse anyone of sexism here - but I had, still in my 'buyer' mode, just strolled over after having an engaging chat in the stall opposite. I had official papers and business cards in my hand. I had a name tag.
