-Go to a bookstore and stare around at the heaping piles of books in people's arms; try to get a sense of arching themes/subjects.
-If there's anything about human nature, psychology, sociology, human anthropology, etc. or anything that's likely to be informative and helpful but in a "big picture" sense, then you're likely looking at an Intuitive.
-Also, observe the people in line; an Intuitive does not stare blankly, but always seems to be lost in thought. However, at the slightest glance, there is a strong sense of emotional intelligence/self-awareness. We'll X-Ray you and not mean to. Feel funny? Also, did I look like I was listening at ALL to yet another offer to get a bookstore card that I have to pay $25 a year for? Whether I sign up or not, I likely don't care about the offer/savings, etc. and just want my books.
-I don't know about other Intuitives, but all I understand is two things about my life: A) Sometimes I have money and B) Crap, I spent it, so there'll be a little underlying tension when I approach the cashier, out of a mixture of guilt and failing to avoid my weakness: BOOKS.
-Don't try to engage me with, "IF you sign up today, you'd have saved $5 on your purchase!" My attention has already wandered; I'm eager to just pay and go. If I don't buy the whole, "Every bit counts!" crap, I'm likely a cynical, book crazed Intuitive.
-Stop me and ask me about what I just bought; I'll be apprehensive at first, but mention the author/past works and I'll truly back up a line to talk your lovely ears off!
