Because the show is totally fake. Everything about it is fake. the truck, the high fives, there's actually not even a brewery called Dogfish head. There's no Sam either. This show is actually an M. Night Shyamalan production, and there's going to be a big surprise at the end. He'll reveal that Sam is just a delusional schizo who THINKS he's brewing beer, but he's really just in his own dream world inside a mental institute.
Seriously though, there's gotta be someone who puts it down. I'm wondering when people are gonna realize that they can just CHANGE THE CHANNEL. If you don't like the show, just change it. I love when I tell people i brew my own beer and they say, "oh, I just watched a show about brewing beer". Can't we just be proud that a fellow homebrewer made it to the point where he's on TV doing what he loves to do, and what WE ALL love to do? He's out there showing the world what we all do. Okay, he's a little quirky about it, but I for one like the show. Sure beats sitting through Kendra, or Jersey shore.
Before anybody says it, of course you have the right to your opinion. Save it.
