The vast majority of people seem oblivious that someone else actually owns that gear. ...
Or that it has intrinsic value, or that someone might have to pay money to repair it if abused.
I often tell the story of an older gentleman who played drums at a church I attended some years ago. He had a very well-maintained set of Pearl Exports, and he played with the most graceful touch you've ever heard. Sure, just Exports, but this is when they started doing those really nice lacquer finishes on them. The set this fellow had was the Ocean Blue lacquer with the grain showing, and he'd polished them so that they shone. Obviously he took great pride in these tubs and there wasn't a speck of dust on them.
One Saturday there was a wedding in our church, and so the staff took his drums, put them in the choir room behind the stage, and then shoved a whole bunch of the black metal Manhasset music stands up against them. A few fell onto the drums.
When he found his drums, they were all scratched up, including one gouge through the finish on one of his rack toms, and his front batter head was torn. He packed up his drums and took them home, and never came back to that church.
Same church, the youth drumset had to have every head replaced because the kids beat on it with plunger and broom handles until they had broken every drumhead. As if drumheads fall off trees or something.
I don't know where this mentality comes from, but I'm amazed how the rank and file see drums in general as expendable toys somehow.
