I occasionally work in various UK locations. This usually involves two flights each way and a hire car on arrival. This is all arranged for me and sent by email. When printed out it's about 12 pages of colour images and waffle. All I want are the flight times, boarding passes and the name of the car hire firm. I think that could be done on three pages. It is a real pain when I'm at a check-in desk and having to find the correct info. I might have to revert to copy scissors and pasting with *real* paste!
Even more baffling is the "Do you need need to print this?" saving paper messages and then having colour logos etc. plastered everywhere.
