Lets look at this interaction so you can learn and perhaps your social engagements may be less uncomfortable one day

1. You Ask the Question
2. You are answered, Given that there is no source
3. You are insulted for complaining before you have any idea what is in the update.
4. You Say your are disappointed because you can't rob all the little banks and get mad money in 5 minutes. If you have been following this game for any period of time you would know that is not even remotely what Rockstar has been talking about. Given again, I wouldn't expect you to know all the details if you were a casual player but save this for later
5. KyleTYBG kindly links you to the official RS announcement what would be in the update. Hence "The sauce"
6. You are told you have no idea what you are talking about
7. You ask for the "sauce" which you then state that you read the IGN review and it says all the heists 3 hours. Which incidentally I also read and the article says no such thing.
8. You are told that the "time" you state is only for 1 heist not all of them.
9. You are told to check your source
10. You are corrected
11. You are told they are replayable
12. You are told yes you can rob banks but it has to be within the heist.
13. You say you want to rob banks not with heists but with liquor stores.
    
14. Its pointed out how fucking retarded that sounds.
    
15. You say vaguely kinda like stores but more complicated which sounds even more retarded.
    
16. You are corrected once again on how long a heist will take
17. Next three posts point out either you are wrong or you are a fucking retard.
    
18. You whine because people are pointing out you are fucking retard because you have some vague idea how you think heists are supposed to work, misread all of the documentation that RS has released and are disappointed in an update you haven't seen yet.
