I had something similar today, a guy texted saying he wanted a two hour booking, with pictures. I stated that i don't allow pictures, which his reply was ok i wont take pictures. I stated that if booking was to go ahead then his camera/mobile would be put in another room during the booking. He hit the roof, and stated he no longer wanted booking. So it looked like my gut feeling was right, always listen to your gut feeling regardless .
