Our HRTM prints enough copies for anyone who wants to take them, and if there aren't any left you can always ask them to make more. I've had many incidents where I've been alone on the floor just to check my grid and see that I'm supposed to have another TM with me that is late by an hour or two. The LOD was too busy running around to notice/check their grid. If I'm dealing with a guest who speaks another language, it's also handy to see who's working that I can call to translate for me...
