"insensitive, much?!"

i'm really irritated when a person speaks in a manner wherein he/she wants me to do something hurriedly!... it's so insulting!... he/she is implying that his/her time is so precious for me to keep dragging on. puhlease!!... he/she even has the nerve to impose on me. all i can say is: "insensitive, much?!"... arrrggghhh!!!
