Donna: Jackie, it's Tuesday.
A subtrope of Room Shuffle.
A stock excuse for going out, when a character either doesn't want to give the true reason or is leaving not to return, is "I'm going to the store". In Manga, Anime, and other Japanese media, the store in question is likely to be referred to as the konbini; i.e., the local convenience store open at practically all hours.
One reason this trope is a lot more prevalent in Japanese media is that they don't have a lot of space in their homes for storage, and convenience stores are generally quite a bit larger in Japan and sell more kinds of things, so it happens more over there.
In the U.S., though, going to get cigarettes or milk or "the paper" is often a convenient excuse to get a character away from the others for a while, and as there are convenience stores that are open 24 hours a day, too, it's not a major expedition, so one character may go alone.

He gets back to the room and falls asleep before he can consume his purchases. What did he do?
I woke up this morning and I got myself a beer!
- Carly Rae Jepsen does a variation of this on "Store" (from her EMOTION: Side B EP). Unlike most uses of this trope, it's from the point of view of the person who's leaving.
