Why do people care about paper?
There are enough trees as it is and everything these days is recycled. The only thing that isn't recycled is people.
For example, it's good to have a hard copy because quite often some staff member will be too dopey to know what to do (I don't mean this specific to HH or any other brand).
Unfortunately I come across so many people on my travels slow on the uptake and after pointing at the pertinent points on the paper, we have a big bingo moment. Quite often this can involve taxi drivers, porters, airport staff. The list is endless - paper is my friend, the signal for it never goes, and nor does it's battery.

I don't want to question the hotel's use of paper!!
