In the front, the Krusty Krab has a parking area, even though cars are usually not seen in it, as well as 5 flags on the roof of the Krusty Krab. These flags spell out R, I, (non-existent flag), U, K. In the back of the Krusty Krab, a dumpster is seen in most episodes. (One episode featured the dumpster across the street.)
The Krusty Krab is usually open from 8:00 a.m. to 6:00 p.m. on Monday through Saturday, excepting Tuesdays, on which it stays open until 8:00 p.m. On Sundays, the Krusty Krab is usually closed, although in "Squid's Day Off" it was open on Sunday, but SpongeBob and Squidward forgot to change the "CLOSED" sign to "OPEN". The restaurant was once open for 24 hours a day for at least 43 days, as a result of Plankton's plan to keep the Chum Bucket open 23 hours a day. It is uncertain how long the streak lasted after the 43 days because Mr. Krabs was too tired to remember. After SpongeBob had a mental breakdown due to exhaustion, and Plankton's plan was thwarted, the Krusty Krab was open for 24 hours a day. It's assumed that the Krusty Krab returned to its usual hours, since later episodes show the employees closing at 6:00 p.m.
