Another thought:

Once my garbage truck didn't pick up my garbage cans, even though I'd had them on the sidewalk in good time.

As soon as their office opened, I called them and I was spouting off about it to the dispatcher, ranting that my garbage cans were full and now I would have to pay extra for them to come back, that they had picked up the neighbors' cans, in general acting as though the guys were just the worst.

Then she said, I'll tell them to swing by agaim and pick them up. It isn't as if they did it on purpose, you know.

I'm a slow learner, I think. It truly had not occurred to me that it was just a simple mistake and not worth an upset.
