Last month, before leaving on a 500 mile route, I carefully printed off the "leave behind sheet" and all other required paperwork, including guidelines (just in case, ya know!) By the time I completed the 5th station, I had those guidelines practically memorized! Which made the rest of the route go much, much faster.
It wasn't until I got home and unpacked the car and found every copy of the "leave behind sheet", pristine, in a folder, that I realized I had never left even one.
Fortunately, the report didn't ask if I had printed and left the "leave behind sheet". If it had, I would have had to 'fess up!!!
