"I once worked with a superior who did not provide any timeline for the projects he assigned to me, yet became extremely agitated when I did not deliver within a few hours. As I had no idea he had such timelines in mind, I requested a meeting with him to tell him about my concerns and that I can absolutely adjust to tight deadlines, however I require prior adequate notice so that I can organize my days accordingly and delegate other duties if necessary - and that I cannot anticipate he would want something done right away upon receipt. He told me he did not realize he had provided unclear instructions and promised to be more clear in the future, which he were."
