I know what you mean. Several years ago I was going through one of those "I'm bored and I hate trucking and I'm gonna quit" phases that we all go through.
I picked up a load of diesel for one of the local lumber mills. It was storming, rain mixed with sleet, and a 20 kt wind, just a nasty day all the way around.
I was unloading in the lee of a shop building so I was out of the worst of the weather. I had a thermos full of hot coffee and a sandwich. Across from me were three lumber trucks tarping dry loads of lumber. They were totally exposed to the weather and they were getting hammered. Two of the drivers didn't have rain gear and they were totally soaked.
The wind kept grabbing their tarps and pulling them out of alignment, They didn't even have boots, just tennis shoes.
They were there when I got there and they were there when I left. I didn't get enough rain on me to even notice.
After watching what those lumber guys were going through, and what little I had just done, I got over my bad mood and started liking tankers again.
That happened to me once. I was picking up a load of sticks with a RR container, and like you say, it was a nasty day in the Badger. While I waited for them to finish loading a flatbed, I watched as this poor guy tried tarping the load, and was clearly being defeated. I couldn't watch any longer, and got out to help. He never would have got it himself and was very grateful. Some places, I think offer tarping pay, but it's not for me.
