When someone asks you to help them with something and their explanation of the action takes longer to explain than the action itself. This is not the best time management. They clearly could have finished the task already. This is especially annoying when the task is making a phone call.
“Call this person, tell them this and this and this….ask them this and that and that…and if they ask this…say that….etc!!!” I sit there thinking “Do you want me to dial, and you can just say that to them?!!!???”
