I think it goes beyond thinking a shotgun is just tool. I shoot with a group of well educated people on the skeet range once a week. Guns well over the $5000 mark. I am only one who regularly cleans their gun. Most might get cleaned at the end of the season or once a year. I also shoot waterfowl with friends who use $2000 plus autos. They never clean their gun until the gas ports or other mechanism clogs up. I don't purport to provide an excuse for them as I don't understand why they don't clean them. I would expect for most it is education why one should clean and laziness.
I also shoot Cowboy Fast Draw and there is a line up at the cleaning table after each round. But it is well understood that after 10 rounds of shooting plastic bullets the fps can drop off by over 100fps.
