Sebastian Hub is the founder of Sub Hub.
In "The Old Country", Hayley and Francine take a cross-country trip at Sub Hub secret shoppers in order to find employees not doing their jobs properly. In Wichita, Hayley tries a difficult order, which is handled perfectly. In Cincinnati, they almost strike out again until they spy an employee taking meat. At first, it appears he's feeding dogs at an animal shelter, but when he strips down and rubs the meat on his body so that they can all lick him, Hayley and Francine move in for a bust. But when they turn him over to Sebastian, he reveals he was using their search to find rule-breakers to party on his party sub and leaves them behind.
