Absolutely, they even require information about specific processes of the working habits in a bank. A merchant ID's, branch numbers of domestic or international branches are sometimes a must have. For example the german police is living strong in bondage with authorities. An unexpierenced police officer can be outwitted by mentioning the name and rank on Phone.
That's why I want to introduce simple tricks with cool examples to sensitize the community for such topics. I have to accept, that this post is more specific about Phone calls, but you can transfer it to an conversation by E-Mail and faked questionaires. By the way thank you a lot for your comment. I should expand my next Post about the possibilities, how the trick can be transferred. :)
