You can also do this with the grapple hook on the d-pad (double tap left and fire) but be sure to do it from outside the room so as not to make Bello mad
Ya know the grapple hook is the only item you can steal with that has a chance for you to get caught on the first try, even the dpad grapple hook is guaranteed
Actually when you find one of these all you need to do is make the shop keeper shoot at you by shooting in his store.. and that will unlock the payday item for free
To be honest your pfp and name is based off the game so you know the stuff, but not everyone does know. Also you do know that the game never tells you stealing is a thing? You need to specifically search it or test it yourself to know.
