He nearly had an "accident" with a phone handset yesterday.
Our telephone system's operator's console broke, so I did some immediate troubleshooting then went to let him know, as he complains when he's not "kept informed".
His response: "What are you telling me for"
My reply, delivered through firmly gritted teeth "so you don't look like a putz when someone else asks you about this, and then come and blame me for not keeping you informed".
