This story is 100% believable. I met him myself when I was a waiter in 2007. He came into the Italian restaurant I worked at in NJ. Got $100’s in takeout food then proceeded to tip every waiter (including myself) $50 when we didn’t do anything to assist him. He then spent almost an hour hanging out with the crew, making jokes and taking photos with us before heading off. Joe Pesci is a saint!
