To know how to differentiate who would accept, I look at those who are well dressed and make up. I always greet them very kindly and explain that I make content for social networks and ask permission to take a few photos. If they don't like them, I delete them and there's no problem. If they like them, I send the photos to them later. With kindness, 7 out of 10 people accept.

If they say no, I don't put pressure on them and I move on.
