There's good and indifferent in every crowd.
Several years ago we had a flat on thee fifth wheel and no where to get off. We were fifty feet beyond the exit.
A Semi Driver parked on the far side of the Interstate to come to our aid. No clearance to traffic lane. He crawled under the fifth wheel and managed to change the tire that way. Would accept nothing. I felt uncomfortable offering it. Not accustomed to much.
Said stick in the offering late and pass the kindness along. We try to do that.
Seen the other side too. Had one inquire but not friendly about air brakes and not having to have an endorsement. Had some valves on wheels bent too the rubber kind with metal in the stem.
Just don't look for things.
