I use email all throughout my work day and do not use elipsis very sparingly and only to express deep thought. My interpretation of an elipsis when others use it in certain cases often comes across to me as they are annoyed or mildly upset with the situation at hand.

Here's a simple example:
My outbound message: Please send me the report by 5 today.
Their response: No problem...

My question now is does anyone else perceive elipsis in this way or am I just too touchy when it comes to interpreting email tone?
