I shot this a few weeks ago, this is at a tube stop, and I saw her as my train pulled up. I made sure my camera was on and ready to fire as soon as the doors opened. I knew I had a small window to take the shot before she objected to her photo being taken. I was lucky I got the shot then she raised her arms telling me not to take her photo. I smiled, thanked her and walked away.
