I have one of those on my shift. We rotate what we're doing every 2 hours, and I swear...the powers that be sometimes are truly TESTING MY PATIENCE! I have gotten to the point that I will trade off certain parts of my job during the night just so I know I won't have to sit near him. I've never had anyone affect me this way, he makes my blood rise just listening to him breathe!!! He's grumpy and angry and mean and always sounds soooo put out by, oh lets see, doing his job!!! He's been there far too long now to leave and do something else, I'm just counting the days until he retires (3 years 8 months!). Luckily I'm not the only one that feels that way too! hahahaha Which makes getting through the night sooooo much better!
Remember to breathe....and just be thankful you aren't related to them! hehehe
