HOW TO AVOID WASTING TIME ON SCOPING VAULT CONTENTS | GTA : ONLINE

So, I'm not sure if this is a glitch, or if people will be banned for it, but basically, what you have to do is: Start a casino heist, and pay the 25k. Then, scope vault contents. Once you know what the content is, while still inside the casino, you need to call Lester and cancel it. Then, go back to your arcade, if you pay again, you'll have vault contents already done, and (i think) a random content in its placee. I say random because i did it off camera to test, I got money the first time, and when I got back, I had gold bars. NGL, I was pretty luck to hit artwork twice. Happy heistin'!
