Generally, once you're able to demonstrate a working knowledge of the inner workings and the terminology of a building's inhabitants, people help you with directions and opening doors.

Generally, once you reach a point where you need to show identification to proceed, people are supposed to be prepared for attack but often aren't.

Generally, once you upload a specially designed program into a mainframe, people expect it to work.
