Is this sceanrio common?

Your manager gives you a task, but the directions are incredibly vague. They don’t have the time or the willingness to give you more information. The worry sets in. If you don’t get it right, it’s going to be bad, but how do you get it right when you don’t know what they want you to do? your heart is in your mouth, not knowing whether you’ve done the right thing or all that work was for nothing.
