I still think the best way to get money is to pickpocket anyone you encounter in the game.
As retail stores become busier, the chance to hide merchandise and pickpocket is easier.
These days, your cash isn't necessarily the most attractive possession for a pickpocket.
"Cash is King", as the saying goes, and while it may sting to lose a couple hundred bucks to a pickpocket or mugger, it's nothing compared to the hell that awaits if your credit profile falls into the hands of more sophisticated thieves.
There is hardly in Robinson Crusoe a scene equal, and there is consequently not in English literature a scene superior, to that where the youthful pickpocket first exercises his trade, and then for a time loses his ill-gotten gains.
