To my eyes, the writing for "For The Room" looks like it was done with a thicker tip. I'm looking at the one that was already given to us before.
After reading your post, I went back and looked at the registration. The writing style for "Lyle Stevik" and "1019 S. Progress Ave" 99% matches the style used for the rest of the words on there!
As for "Suicide", I'd wager that the pen was either a 0.5 or 0.7 point.
For me, the registration now throws a different light on the name and address of choice. How do we know if he even gave that name and address? Looks like the name and address might be a work of fiction in a whole other way. What if the desk had something for that particular Best Western laying around somewhere?
I have to fill out mine and my grandparents' last names, the day of the week, times of arrival and exit, and apartment # before I can visit them; and this woman can't figure to fill out a date on a hotel registration form, exact or otherwise?
