So I was cruising around as Michael when all of a sudden I spot a store that I can go inside of, but it isn't on my map. Sure enough I went inside and there was nothing to buy, so I pulled out my gun and aimed at the clerk and then demanded all the money. The clerk fills a bag with money and throws it at me. The cops were alerted but it was an easy getaway.
Only got a little over $300 but it was cool nonetheless I've been so busy doing a the campaign that I didn't take the time to look for stuff like this. But I'll keep looking some more.
I'm not too good with directions, but according to my map it's right near Vespucci Canals, across the road from a Ponsonbys store.
