Somewhat annoyed right now.
I made New Year's Eve plans and the schedule person at work put me in a shift for New Year's Eve without telling me. I had to try like a lunatic to get rid of it.
And I also really, really, REALLY hate big last-minute changes for something I've been planning for two weeks. It annoys the hell out of me when people can't stick with a simple plan and go all over the place and make everything a last-minute messy hassle when it could have been so avoidable. Ugh.
