Never. However, this one time, I was at work, and I answered the phone. And it was the wife of one of the guys I worked with. And in the background there were... sounds. She said "can I speak to my husband please?" and I said "okay". I put the phone on hold and then grabbed the microphone to announce that he had a phone call (as per the protocol), but then I realised that the... sounds distracted me and I hadn't remembered who she was asking for. So I picked the phone back up, there were the... sounds again and I asked who she was after again. Then I remembered and made the page and he answered the phone and I spent the rest of my shift wondering what the fuck happened. He's a great guy, very accident prone though...
