I guess each street photographer has their modus operandi, but we share one thing: the need to not influence what is being captured. My approach is to not stand out in the crowd, to be a part of it in a way that people go about their business as they would. I started shooting street with a long focal length, now I usually 10mm to 50mm which allows me to be in the scene.
We should adopt a natural body language, do not look sneaky or suspicious. Pretend you're shooting the buildings if you must, but do not shoot and disguise.
This technique allows us to keep everything in focus, so everything you point your camera at will be captured. Once you master this technique, you can let your camera hang from your hip and discreetly shoot. I use it in closed public spaces a lot. Here: http://shadowness.com/damien-c/kick-it at f8

thank you thank you would love to improve my skills with street photography one has to remember since i no longer have my telephoto lens,as back then i could really close in on my subjects.Any way that doesn't stop me in doing street as i simply rely on camera lens
