Depends on the incident. A lady who knowingly goes into a crowded coffee shop without any kind of idea doesn't warrant help. There's no law saying she couldnt have put her shit down and then gotten in line with two free hands. I do that all the time when I'm carrying stuff. I've caught with shit trying to help people who didn't want, or dealing with my own problems, or actually stepping into slightly more serious situations. No reason to waste my time and energy on somebody going out of their way to give themselves a hard time. Most of the time somebody else's problem is actually somebody else's problem
