At the Krusty Krab, SpongeBob notices that Mr. Krabs is filling a hole in the wall with toothpaste. The toothpaste begins dripping and causes the hole to crack, making an even bigger hole in the wall. A fish and his children came to the Krusty Krab and orders from the hole, thinking it's a drive thru window. This gives Mr. Krabs an idea to create a Krusty Krab drive thru. SpongeBob brings in equipment for the drive thru but Mr. Krabs just uses a simple menu written on napkins, and a microphone with tin cans. A customer soon orders from the drive thru but SpongeBob has trouble getting the food out of the window. Later, Plankton drives by in his tiny car (and no one sees him) and an old man runs over him, then he drives away after he thinks Squidward said they were closed. The next customers are Pearl and her friends; they play a prank on Squidward by screaming through a megaphone, and ends up getting his ear replaced, making Mr. Krabs pay his bill. After that, Larry the Lobster shows up, accidentally breaking the drive thru microphone with the side of his SUV. SpongeBob then has trouble getting his food up to the window of his SUV and drops it on his head, so Mr. Krabs hammers a second hole in the wall much higher than the first. Soon, there is a huge line through the entire town to go to the drive-thru. The mayor comes and isn't happy about all the cars, so Mr. Krabs solves this problem by breaking a hole for another drive-thru. Then, SpongeBob and Squidward desperately try to feed all the customers at both sides. It ends up with a car accident and Plankton gets run over by an old man again. Mr. Krabs breaks another hole and says "More money!" Then, the Krusty Krab cracks and falls apart into a pile of dirt. The episode ends with Mr. Krabs crying.

Running gag: Mr. Krabs smashing holes into the Krusty Krab with a mallet; Plankton getting run over and squished by the old man.
Mr. Krabs's drive-thru idea is nothing new. It was featured in a previous episode, "Driven to Tears" (SpongeBob manned it but Patrick interrupts him). The difference is that Mr. Krabs had a real drive-thru window and microphone in the earlier episode.
There was a small drive thru window in the first three seasons. After season 4, the window disappeared.
Mr. Krabs used so-called "junk" instead of the things SpongeBob bought because he said it was free. However, if SpongeBob already has it, it is presumably already paid for by SpongeBob. So using it would not cost Mr. Krabs any money.
Though it is possible that Mr. Krabs was trying to avoid the use of technology. As heard in "Krusty Krab Training Video," Mr. Krabs keeps the balance of technology in check at the Krusty Krab due to his fear of robot overlords.
Despite this episode being the main episode to have a drive thru, "Driven to Tears" was the first episode to feature a drive thru.
The side walls of the Krusty Krab are wooden instead of glass in this episode for an unexplained reason. This is so far the only episode where this occurs.
Squidward said that he wished he had gone to college, but in "Atlantis SquarePantis," he said that he learned more about art in Atlantis than he did in four years of community college, indicating he did go to college. It is possible that Squidward meant that he wished he had gone to college longer or a university.
Two ways of Mr. Krabs being cheap are shown: smashing a hole in the wall for a drive-thru window instead of having someone install one properly, and using old napkins as a menu board and tin cans as a microphone rather than the microphone and menu board SpongeBob bought.
This is the second time a "telephone" made out of two cans and a string is used. The first was in "Fools in April"/April Fools.
When Squidward says, 'That's nice, that's interesting', it was a possible reference to "Someone's in the Kitchen with Sandy," as it is the same thing said by Plankton in his Texas drawl voice as he impersonated Sandy.
When Squidward says that his ear hurts, he looks at the screen, and happens to talk to it, which breaks the fourth wall. Plankton also breaks the fourth wall, when he looks at the screen as he pulls up to the drive thru and says he's going to order a Krabby Patty.
At the point where Mr. Krabs tells SpongeBob to get the order for the policeman, SpongeBob appears though the kitchen window. Eariler due to Squidward's complaining, Mr. Krabs moved SpongeBob and the grill to his office and moved his desk to the kitchen.
When the green and blue fish collide with their car, the green fish's underarm is orange for a second.
There appeared to be a large traffic in the drive thru, filled with hungry customers. However, the customers could have just entered through the front door and ate inside if they were so hungry.
The left and right sides of the Krusty Krab are windows. In this episode, they're solid walls.
However, this may been done on purpose so they tell the plot.
