I would, without a problem. Although we don't have a postman, we have boxes, but yes, I would let the meter reader in, but I do not pick up hitch hikers.
I typically don't. Funny story though, I was on the TC going into Winnipeg and a young female had just set herself up at the roadside to thumb a ride. I was travelling too fast, could not stop (I would have). The guy travelling behind me stopped and picked her up.
She was at the side of the road only moments.
Days later I travelling Hwy 17 between the Manitoba-Ontario border and Kenora at 2 in the morning and passed a car on the side of the road with four way flashers on and a fella waving me down. I pulled a U turn and pulled up behind the guy. Turns out he was having battery/electrical issues and had been waiting for someone to stop for hours. Countless cars passed by and no one would stop.
I noted this guy had his wife/girlfriend in the passenger seat. I told him if he needs to flag down help, have her do it. That hours long wait would turn into mere minutes.
