Biz cards and telephones
Struck a chord with me because on Friday I gave my card to someone and had to tell them not to ring the landline number on the card.
Because in a year and a half it had rung only twice.
So I got IT services to take it off my desk.
Everyone uses my mobile number anyway.
Of course I currently have a large box of biz cards in my drawer and all of them feature the number from the phone I had removed.
