Was having trouble w/ Ppad sending message to disp. Figured at a pup stop I would call in... Was informed that disp was down hard, and by the way here are your new oncalls. This was at 16:20. Hear a knocking on my door. Guy standing there informs me he is #$%^# from district saftey doing an onroad saftey check. asked for my emp #. says thanks and turns around and walks away. Gal at disp was laughing her off.
