What is it like to do street photography in the middle of tons of people, with people on it.

I'm a rather socially awkward anon but I would love to photograph the cities and the people in them. (Not single portraits, but crowds of people and groups of people who appear on photos of the streets.)

I'd expect you'd regulary end up getting people coming up to you and sperging out over being on a photo you just took. This would be hella annoying to deal with. Especially for socially awkward people. However city photography fascinates me a lot.
Conflicted anon right here.

Anyone does photography like this and can tell of the experiences? Do people just let you do your thing or do they come up and start talking or even bitching to you?
