Robbing stores is pretty simple. Just take out your gun, and you have access to the cash register and all the stuff in the store. If you're robbing a clothing store, you need to actually go up to the piece of clothing to take it, rather than doing it through the clerk. It seems obvious, but it threw me off at first.
Kind of off-topic, but they actually thought about robbing pretty seriously when they made this game. I robbed a clothing store and left the clerk alive, and then went on my way and did other stuff. 5 minutes later I went back to the clothing store to get something new, and the clerk was there talking to police officers, and shouted to them that I was the guy who robbed her. Thought it was pretty cool.
Yea, also you really don't need a gun either since during the demo, I went to the bar and just fight the bartender with my fists and just robbed him there. So I think it's quite good that there isn't just one specific way to do the free-roam stuff like in other sandbox games. And yea least the A.I. is mostly smarter though the cops can at times be like those from the Blues Brothers and all just try to crash into you lol.

Yeah Jules, it's like that with any. If you go into a store and just murder everyone, I think it has to only be the owner actually, but whatever it's more fun to kill everyone anyways, cops come along after a bit.. Check everything out, and then a little later on when you come back it's all sealed up, I think it's a nice touch. :D
