Recently had a "incident" when I found out one of my doctors didn't have email and I needed to get a form to them to complete and send back before another different doctors appointment. Normally I'd just sigh and drive back but this doctors office would have been another 1hr round trip.
Ended up signing up for a free efax trial then worrying all day as I didn't get the form back. Call in the morning and they had decided to just fax it to the other doctor for me, and did so shortly after they received the form, but didn't think it important to tell me. Murder definitely crossed my mind a few times that day.
