Yesterday we asked how much change you need to fish out should you wish to make a call at a BT phone kiosk. Crickey. It's been a while, huh (there's the rub for BT, which hopes variable pricing may halt the pay phone's slow demise). A massive 60% of you thought it still cost 20p, while one-third correctly answered 40p. The rest opted for 60p. Today's mini-question is on the Magazine index now.
