Oh it's very easy, although when I first started I was very nervous. I even used to go out with a 85mm to 105mm lens. Now I go up to people with a 35mm or 28mm lens right in there face. What's strange is that I got more trouble from people when using the longer lens.
A blog I wrote on some of the runs with people is here [link] If your going to do street work in the style of PHILIP-LORCA diCORCIA a long lens is fine as it is about singling out portraits from a crowd. I'm more from the Capa, Winogrand school, where it's about filling the frame with a scene, more suited to wide angle lens's. I've tried a few times to use long lens, but when I saw a scene, the more distance from the subject the more likely someone is to walk in front of your line of sight.
I think bang for your buck you can't get a better lens, I've compared it to my 50mm Leica elmar for sharperness there the same, although the leica has better bokeh. This reminds me of your photo of the woman and baby on the tube.
