In order to rob a store you must do the usual run of shooting up the store in order to get the money. The money the clerk (doesn't matter if its a npc) gives you, you may record inside your bank.
You may ONLY ROB STORES ONCE PER ROLEPLAY
After you run outside of the store to get away you must announce over game chat which store you robbed. Such as listing important areas around it. Masks are recommended, but of course not required while robbing, but if you do have a mask on you must state such while announcing the location of the store of which you robbed.
As of now there will be no bank robbing, since I have yet to find a bank.
