The Florida pizza guy, Scott Van Duzer explains:
Everyone thinks it was scripted. Everyone thinks I asked the Secret Service. I didn’t ask the Secret Service anything. I didn’t know what I was going to do. You know what I mean? He just came in, and the way he came in was so genuine and warm. He came over to me like he had known me for 25 years. He said, “Where’s Scott?” He opened the door and I was standing right there. He gave me a big high five, and started talking about my biceps and muscles. He said, “If I eat your pizza, can I get some muscles like that?” We were just fooling around. He gave me this pat on the shoulder, and that’s when the big hug happened.
