Waiting is an action in Fallout 3 and Fallout: New Vegas. It can be used to wait for a period of time. Waiting is useful for getting into stores that close a specific time, and waiting for the sun to come up or go down. In the PlayStation 3 version, it is done by pressing the "Select" button, the "Back" button on the Xbox 360 and the "T" button (by default) for the PC.
In certain circumstances, there may be times when you are unable to wait. You cannot wait while enemies are nearby, when trespassing, while in the air, if you are being irradiated, during dialog, or in water.
Waiting is a useful tool when dealing with Caravan Merchants. Travel to Canterbury Commons and wait for two hours by the large tree in the center of the cul-de-sac on the western edge of the town. If the merchant you want does not appear wait another two hours. This way you can cycle between merchants quickly. Other places you can wait for merchants at are by the Rivet City platform, outside Megaton, Temple of the Union, Agatha's house, Paradise Falls, Arefu and at Evergreen Mills.
