Therein lies the problem. "Ask" people force someone to say no and saying no is considered rude. "Guess" people are then forced to be rude when they don't want to be rude, and knowing this, are forced to be polite and give in to your demand. Obviously there is nothing sinister going on here, but unwittingly, "Ask" people are creating a uncomfortable situation for people who consider it rude to decline a request.
