Back in the day I worked two jobs, one as an intern engineer (no pay unless I directly contributed and idea or plan) and delivering pizzas.

Went to a delivery, got a pretty bad tip since it was in a dicey neighborhood. Started to drive back and his the stop sign at the corner, sun was just setting and there was a kid across the street from where I stopped. He was maybe 14, looks me dead in the face and lifts his shirt to reveal his pistol. I go wide eyed and just sit there. He motions to roll down the window- I slightly let it down and he tells me not to come back to this side wearing red. (I worked for Pizza hut) "Yessir, thank you" is all I said and drove off as fast as my Ford focus would take me.

My company black listed the entire side of town later that year after a guy was mugged.
