Synopsis
Plankton is once again complaining about how he has no customers, with Karen being annoyed by the constant whining. Nat Peterson, instantly comes in and asks for a Chum Stick. Plankton at first thinks he is kidding, then Nat says  he was serious, then gives Nat the Chum Stick. After Nat eats the Chum Stick, he says the Chum Stick was so good, he would come back the next day. Plankton is overjoyed at the fact, and brags to Karen, who is barely shaken by the fact (A possible clue that Karen is actually paying Nat.) Plankton decides to wait with a Chum Stick for Nat. Eight hours later, Plankton wakes up by the clock and realizes it's closing time, and concludes that it was not true that Nat was coming back. However, at that moment, Nat appears. Plankton gives him the chum he had been saving, which Nat thinks is perfect after he looks like it was a very appalling meal. Nat says he will come back the next day and the next week, telling Plankton he has a regular customer on his hands. At the Krusty Krab, Mr. Krabs is bowling, using his money as the bowling balls and pins. Plankton appears, and Mr. Krabs tries to squish him with a spoon. Plankton assures Mr. Krabs that he doesn't need to compete with the Krusty Krab anymore since he now has a regular customer. Mr. Krabs laughs at him, and shows off all his customers eating Krabby Patties. Then Nat appears asking Plankton for another Chum Stick in front of Mr. Krabs. Nat carries Plankton back to the Chum Bucket, with Plankton mocking Mr. Krabs and insulting him. Mr. Krabs explains the situation to SpongeBob, and orders him to get Nat to eat food from the Krusty Krab and not at the Chum Bucket. Every attempt is unsuccessful, first when SpongeBob simply shows Nat a Krabby Patty, which Nat immediately doesn't like just by smelling it, secondly, SpongeBob fakes a trip off of a rock holding Nat and  pretending the Krabby Patty is coming straight for his mouth, thirdly, SpongeBob transforms into Karen and pretends to give Nat a chum stick which is a Krabby Patty, he ties up and gags Karen so they won't notice him, fourthly, Mr. Krabs and SpongeBob trick Nat into going into a shortcut leading to the Chum Bucket which really leads to the Krusty Krab, they make chum Nat doesn't like. Mr. Krabs bursts into tears, saying that he cannot afford Plankton to have even just one customer. SpongeBob says that if he wants Nat to eat at the Krusty Krab, he will have to make chum as good as Plankton. This gives Mr. Krabs the idea to steal the chum recipe.

That night, Mr. Krabs sneaks into the Chum Bucket trying to steal Plankton's recipe but Plankton catches him with the spoon security system. SpongeBob then grabs Plankton and starts talking about irony of the situation, but Plankton then uses the spoon security system on SpongeBob. After Plankton reveals the name of his system, Karen shows, on screen, that Nat is heading for the Chum Bucket with a fortune. Nat comes back telling Plankton that the Chum made him sick twice, since Nat only pretended to like the food so Karen would pay him, SO that Plankton should stop his self complaining, Because of this Plankton once again feels miserable again, and realizes that he never had a regular customer. SpongeBob tells Mr. Krabs to escape, but he decides to stay and laugh at Plankton's misery, which enjoys seeing Plankton cry.
