The shop opens at 9 a.m. and closes at 9 p.m. However, if Seagrave can be found wandering around the other parts of Rivet City when the shop is closed, he might still have the option to trade, no matter how far away he is from the actual store.
The locked boxes in the store are empty.
If the player approaches Seagrave and begins conversation with him, one of Seagrave's opening lines will be, "I've got a little bit of everything." The player can then respond with, "Do you have a suit of T-51b? No? Then you don't have everything." He will react confused and annoyed, telling the Lone Wanderer to go elsewhere if they want to fool around.
