Office politics

In a hallway of a hotel or office building, I’m in a standoff with 3 other people. Am I after them or are they after me? I see a clock on the wall and the reflection of a gun on its surface. I make a move but a man yells “Not so fast!” and throws a stick of dynamite down the hall. I run for it but am hit with a dart. I don’t know if it is a tranquilizer or poison. I pull it out and head for the elevator. I have to wait for several people to get on before I can enter.
