Throughout Vice City there are 15 stores that can be robbed. It may not seem like a major part of the game like missions or properties, but robbing all the stores contributes to getting 100%.
8 – East Island
7 – West Island
So (without cheating) you’ll have to unlock the rest of Vice City to get all the stores.
How much money you rob differs from store to store, once you aim your weapon at the cashier he will give up a “wad” of cash, but at the same time you’ll receive a wanted star. If however you keep aiming at him, he’ll fork over more cash but you’ll get another wanted star. It’s easier in my experience to just get the first amount of cash and then shoot him. You’ll only have one wanted star (which will go fast) and the store rob will still count.
The weapon doesn’t need to be an auto-aim weapon, as I found out today. I walked into a store and aimed my M60 at the cashier, only for him to push the alarm and get me 2 wanted stars. So as said above, if you don’t want too much trouble just kill him quick.
I have marked blue dots on this map to show where each store is located.
