Failure to stop behind stop signals, stopping in crosswalk/Bike Path

Riding on a Bike Path and Had a green light to proceed. The John Henry Plumbing truck breezes right past his stop and stops in the crosswalk wihtout even looking right.
I tapped on his window to remind him that he needed to stop behind the stop sign and never in the crosswalk before looking both ways, as per Nebraska DOT drivers regulations.
I had to knock harder to get his attention and lower the window where he basically told me off.

Just a reminder never to use John Henry plumbing services. They have people with lower than average intelligence working for them.
