After accidentally creating a large hole in the wall of the Krusty Krab, a customer mistakes the hole for a drive thru window and places and order. Mr. Krabs, being a the savvy businesscrab that he is, quickly adds a menu and microphone system to facilitate the drive thru. It becomes so popular people are waiting in line and causing a huge traffic jam (could use this to talk about a negative externality too!) in Bikini Bottom. The police visit and threaten to issue Mr. Krabs with a ticket and then the mayor comes in to complain as well, but Mr. Krabs has a solution. Adding a second drive thru to reduce the line, but that doesn’t work out too well. Watch what happens as diminishing marginal returns sets in.
