Just last year, I was in NYC and riding a packed subway. Mid-ride, a man gets up with a strangely large backpack. He cleared his throat and said, "Alright everyone, the time has come-" and in that moment the people on the sub's faces turned to fear, a mother nestled her son, and I tensed up, ready to pounce. He continued to say "-I am a poor man, in need of food, if anyone has anything on them or if they could take me out for food it would save my life." My girlfriend and I got him some KFC and asked him to approach a large group of people differently. All in all, he was a nice guy- didn't even look homeless. My girlfriend still refers it as "The day the KFC guy was 'gonna kill us".
