I am fine with non-routine things unless they directly contradict my routine. Even in the short term, if I am going upstairs and someone asks me to do something, I have to go upstairs and then maybe consider what they have said. I would be devoting all of my attention to going upstairs as "the thing that I am going to do now" and I get angry when someone interrupts it.
