The level of safety depends on where you are. Generally they’re as safe as anywhere and you should take standard precautions. But when you’re somewhere that you stand out as a foreigner, and especially if you’re in a place where every foreigner is seen as rich, you might want to be a little extra aware.   Often it’ll just be people coming up looking for a handout or trying to sell you something now that you’ve got a pocket full of money. My recommendation is to walk a little distance away from the ATM before hailing a ride or engaging in business with anyone.
