There are a lot more people like that then most believe, esp. in small towns or rural areas.

My wife learned that on our Honeymoon in mid Dec 73. She is LA Metro Area born and raised. We got to my hometown, my Grandmother was at my Dad's in St Louis for Christmas but my Great Uncle, next door, gave us the keys to the house. Well it snowed about 6-8 inches that night. Small town, no sewers, ditches with little bridges for the driveways and the snow had the bridge hidden and we were going to my Aunt's for an early home cooked country breakfast. So I waded into the snow and was guiding my wife in backing the car across the bridge, ice under the snow, one rear wheel slipped and dropped off the edge and the car was bottomed out on the bridge.
Two pickup trucks with about 6 guys driving by came to a stop, and they all came running over and grabbed onto the rear bumper and helped me lift the wheel back on the bridge, and one of them took over steering until the car was in the street. They asked me why I was back home. I told them we were on our honeymoon from Los Angeles. Debra tried to pay them, but they all laughed and waved her and the money away as they ran back to their trucks. One of those guys was from my HS graduating class, and he just yelled, "Explain it to her how things work here. We have to get to our goose and duck hunt before all the good blinds are taken." And off they went.
She was amazed that you only paid for help when you hired someone for it. They had volunteered, so no pay, in fact it was almost an insult to offer money when they volunteered. A lot different from what she was used to.
