>> how about i give you $40? >> well, i can't do that, sir. i've got rent to pay. i have bills. and the kids need to eat. >> reporter: henry handed over $300 in cash, genuinely believing the suspect needed money but highly skeptical for what reason. >> he told me he needed the money for his kids. he looked like 65 years old. it's not true. you know, because if you're 65 years old, you are not going to have kids. >> reporter: the robbery happened around 11:30 saturday morning. the man did nothing to conceal his identity. his every move captured by 14 surveillance cameras inside and outside the gas station. before he calmly walked away, he made john henry a promise. >> thank you very much. i appreciate it. and i really am sorry. if i ever get back on my feet again, sir, i'll bring it back. >> and that report from komo's ray lane. now, criminal records indicate the suspect has already been convicted of another armed robbery. that was back in 2004. and he did three years behind bars. kind of a sad, bizarre story. it's funny too, on his way out,
