I would suggest that by asking a question like this, you should re-think your approach to the subject. Perhaps it is not about sticking your camera in someone’s face, or having any angst or hyper attitude when taking the shot, but complete relaxation. When considering street photography, why not try and learn from the greatest master of all time, namely HCB. To illustrate this point, let’s look at his picture that appeared on the cover of Picture post, with the caption “Military appraisal at Moscow trolley stop” taken in 1954.

If you go to a location where people wait and wait with them, after an hour or two you will dissolve into the invisibility of just another person waiting.
Having said that the shot in illustration is quite amazing. If you read HCB quotes, one of them states – “The difference between a good picture and a mediocre picture is a question of millimetres – small, small difference. But it’s essential. I don’t think there’s so much difference between photographers, but it’s that little difference that counts, maybe. - Henri Cartier-Bresson - quoted in the interview by Sheila Turner Seed. [cited in: “Popular Photography, May 1974, p. 142 “Henri Cartier-Bresson”]
Now, you may say that quotes like this are bullshit, but just look at the profile of the woman on the right and the small dark line separating the woman behind, who incidently, if not standing is walking in a direction to cancel this out.
