Just an anecdote:
Years ago, loading my car in a Costco parking lot in the dark of winter, I was approached by two bums asking if they could help.
I'm offered help by bystanders all the time, and I appreciate and accept it all the time. These were bums.
I returned to the store, bellied up to the service counter, and said, "I was just approached or accosted, take your pick, by bums in the parking lot. If you can't keep your parking lot safe, I'm not coming back." The clerk disappears.
Seconds later, the floor shakes with about twenty guys running out the front door.
Returning to my car the two men were nowhere in sight. And I appreciated it. And I don't apologize.
We had recently had a 19-year-old mother of two shot and killed at a stoplight by a panhandler. And another young mother had been killed in a convenience-store robbery
