well, the question I am asked mos often is 'are you a professional?' followed by 'what brand I like and why'. Some people ask to see my photo's and of course I then show some. And sometimes they ask me to take a picture of them. It's mostly friendly inquiring and I always ask people if it is allowed to make a picture of them (I love street photography.) If you ask nicely, they mostly agree, but if they don't then I follow my way...
