Hey, it could have been an obnoxious, d'nozzle message like the one left for member Grant Eaton:
(Bizarre mixture of upper and lower case letters indicates that was probably written by a serial killer, by the way. )
Looks like someone has anger issues. Grant should have looked up the address for that company and then mailed the note back to them with the time and place it was left. Maybe they would do something, maybe not.
