You can already rob stores... have you even tried Deffpony? You have to aim your gun at the person before you enter the store, and then you can open the door so you can go in and point the gun at them. Then, they'll take like 10 seconds to empty the register, and throw a bag of money at you when they're done.
Yea someone just showed me this. Thanks Im gonna remove it from the OP
I didnt realize shooting the registers would give you money. I just tried right on d-pad
No... did you read it? You aim the gun at the person (once you're inside), then they empty the register, and throw a bag of money at you.
You can also just kill the clerk and shoot the register, posted video above.
