A man came this morning to change a lock on an office door. I took him to see the door in question, whereupon he asked me if I had a key to it.
Well, no, that's why we need it changing. If we could lock it, we wouldn't need a new one, it's not just that we got bored with this one.
Then he rubbed his chin and said - "Well, I haven't got a lock with me, I'll have to go and get it." But you came to change the lock? You knew that. Your office is on the other side of the site. And now it's started to rain and you're going to get wet, hah!
Was just speaking to someone off site, and they asked for another member of staff's home phone number. It wasn't till I'd read it out and hung up that I realised I'd just read out the number that she was actually on herself, cos it was the same area code....oops!
