Frank, played by Mitch Hedberg, is a man who may have used to work at the Hub, as he has only been shown in Eric's Buddy.

Frank is depicted as being a sarcastic jerk, making witty comments towards his customers. An example is when he was arguing with Kelso, saying that he did not lose a leg in the Vietnam War just to feed teenagers (which is true, since he has both legs). He also orders Hyde to buy something or leave, which he at first does but then comes back in and orders something because it is freezing outside.
