I tell them I charge for my time talking on the phone and ask them for a credit card number. If they continue I keep asking for a credit card number telling them I will talk to them as soon as I have a billable account. Was riding on a cross-country trip one day and answered a call out of boredom and demanded a credit card number to listen to his spiel my buddy driving was laughing so hard he almost wrecked the Jeep.
