I have found that waiting outside provides oppurtunities for taking photos of people in their natural settings as they go about thier business. There were 3 doors waiting for a lady outside the pharmacy - I guess they follow her everywhere she goes.
I really should take more portraits but I rarely take full on headshots upclose which is the only way to get clean portrait picture with the 28mm lens that I use. I have to be really close to the subject - I mean really, really close.
Saw it on the menu, tried it out but did not like it. Reminds me too much of KFC. I prefer the original. But others have found it interesting or even desirable.
