I work with about 30 women and we do like to chat and have fun. But when we need to know about attendance for a lunch meeting, or childcare resevations, etc... the director sends a no fuss-no muss e-mail basically like what your friend sent.
Business is business. You can chit-chat and be friendly at other times. But if you had to call of them to confirm what they should have already done, then you would be on the phone all day, and still have not gotten all the info!
If their "feelings" were hurt, then you could simply explain that you had a horrible cold and could not make calls. Maybe you could preface another e-mail wih that info.
documnet, document, document
because if your friend is in such a job industry that feelings matter more than performance, they need to show how much they worked, regardless.
