Role playing
As in playing the role of someone who wants to buy double glazing/doesn't mind taking part in a questionaire.

The double glazing salesman:
stranger: "have you considered replacing any windows or doors in your property?"
me: "yes"
stranger: "how many do you want replaced?"
me: "47"
*click*

The time I took part in a survey randomnly answering "yes" or "no" to each question, went on a while until this point:
stranger: "do you have any children?"
me: "yes"
stranger: "how many?"
me: "no"
stranger: "what?"
me: "errrr, yes"
*click*

Always come unstuck on the "how many" question.
