What I learned from watching Fletch.
1. Junkies hanging out on beaches are not startled at all when a man in a suit comes out of nowhere and says "excuse me". They will just say "yeah" and politely begin a conversation.
2. Newspaper publishers will run full page advertisements steering their readers to upcoming stories, whether the stories are done or not. They will take a leap of faith that their reporter will finish the story by the publish date, and that the story will need absolutely no review, editing, etc..
3. Waiters at country clubs simply accept at face value the claims made by random people at the club, and will gladly place $2,000 lunch orders without verification.
4. When a conference is crashed by an unknown person, everyone at the convention will simply sit on ther hands and watch it all happen. No one will say "hey, who in the hell are you and what the hell are you doing?". Also, they will make no connection between the crasher and the several cops who have suddenly entered the room.
5. Everyone is clueless to ultra hip name dropping references. When someone identfies themself as Ted Nugent, Igor Stravinsky or G. Gordon Liddy, no one will grasp that the name belongs to a prominent historical figure.
6. Security is nonexistent; anyone posing as a doctor, airplane mechanic, SEC investigator, etc., is free to move about at will.
7. People hired to "look out for the place" will point a loaded gun at intruders and attempt to learn their intentions, and then say they will call the cops when the question is not answered satisfactorily. They will not call the cops first, as it is a common occurrence for people to simply walk into vacant houses and have a look around.
8. People can take one look at another person and determine that they have the same bone structure. Also, from a distance of 20 feet or so, a man can determine if another man is wearing his suit. No two suits are alike.
9. Dobermans can be trained to jump through glass windows, after which they won't have a scratch and are not bleeding. They can even be taught to open doors.
10. If you want to find out who will be sitting next to you on your next flight, simply walk up to the ticket counter and ask. They will even say who bought the ticket for the person sitting next to you.
