Robert seems like the least valuable shark

What expertise does Robert bring to entrepreneurs? I get that he’s been successful himself but I can’t think of the last time he’s been “the right shark” for a deal. He seems clueless, jokes around too much, and doesn’t seem like he’d be a great mentor. You’d think the Jaju pierogies would have been a slam dunk for him since he’s Eastern European and grew up eating them but refused to do the deal without Daniel. He’s just a wasted seat up there and he’s annoying to watch sorry!
