Monkey business...
They steal from you (be it: specs, umbrellas, cameras, etc) and trade it for food.That's how they make business.Monkeys are everywhere in Bali, to name some are: Uluwatu, Ubud, etc.My advise is to keep all your loose items in a bag and hold it tight and wear contact lenses instead of specs hahaha...And if they ever managed to grab something from you, don't try to take it back by force.They have big and sharp teeth, I've seen monkey fights there and one of them got a long, deep flesh cut.
