i agree on that people have to think things as theyre shooting. as i walk down the street i can pretty much imagine a shot before i even take it. I usually shoot on instinct rather then waiting for things to develop. It might be hit or miss sometimes but when the shots are good ones they're usually far beyond expectation. If you wait for the one perfect shot you might have missed several other opportunities at even greater shots. IMO
that person could have taken that shot with a 50mm lens or even a stock lens without having to crop and he would have had a nice depth of field as well.
Great shots Spaceman
