I am not sure whether (most probably yes) anybody noticed ....but when the fireman was talking or shall i say 'teaching' us about the stuff you need to do during a fire,he was erm..looking at a guidance paper/book. I was wondering whether the firemen need to consult a book during a REAL fire?

Shouldnt they already know EVERYTHING by heart?

OR they are just afraid of teaching us the information?
