habbit i guess, its cause at a old place i worked at when invoicing of you used the space it would ignore it and print the comments towards the left and not highlight the notes but if i wrote
,,,,,,,,,,,,,,,,,,,,,,,,,,, RECHECK PART NUMBER BEFORE LOADING VAN ! ,,,,,,,,,,,,,,,,,,,,,,

the 30 percent of drivers would actually read it,,,,,,,, 10% would actually do it though

it was the best way to get messages noticed,, and i use it still and the place i work now
