In case you were wondering how this belongs in rActLikeYouBelong , the entire thing starts with social engineering people hacking , as does a large majority of cracking computer or otherwise operations begin . As they state , People are the number one weakness , from a security perspective , in any organization . They infiltrate the premises by acting like internet service provider technicians . An observation while they are getting their visitor badges was , He ' s doing a lot of sighing , which is typical of what you should be doing . Kinda creating a sense of inconvenience . Hoping to play on her , you know , willingness to wanna help people . They got away with it because they had a plan of action , knew what they wanted in advance , and were practiced in their roles . Which I think a lot of getting away with acting like you belong takes regardless of context Knowing what you are trying to achieve , having the right lines to say when confronted , and having the confidence to play the expected role . And really , this holds true to any complex social interaction .
