I do not think this is trait related, it could be but I think I have a theory.
I played one of my sims last night and before he went to work I set up his action, eat, shower, pee, woohoo with wifey. Then I put the game on speed 3 and waited, Then just as there was about 15 game minutes before he was due to go to work I realised that he would not have enough time to woohoo, so I cancelled that action in the queue right before they began. He stood there tapping his foot until he was late for work. I think this foot tapping lag has something to do with the game mechanics, it seems that when a task is cancelled sometimes it is stuck in the background as an action and the sim can't do enough else until enough time had passed.
If I find the patience then I will play test this, by playing without cancelling tasks that has been started and see if those sims will stop their foot tapping at me.
