It used to be that an organist had to be nice to at least one person. That's a calcant who pumped the bellows. Just try to be mean to this guy. He will just say, "I'm not pumping for this jerk." And there goes your postlude.
The farther into history we go, the nicer an organist had to be. In Winchester Cathedral they built an organ with 26 bellows in the 10th century. Imagine how many calcants did you have to be nice to then?
I think it's the electricity's fault.
Now you have the blower, right?
"Oh, you couldn't talk during my prelude? Try that during the postlude with all stops drawn out!"
"You think the tempo of my hymn was too fast? OK, I will add improvised flourishes between the phrases to slow things down a bit!"
"Your hearing aid can't stand this high-pitched mixture?" I'm sure you can deal with the Cymbel!"
You can just keep kicking other people, keep slapping them in their faces because the blower doesn't care.
"Oh, you want to play an organ in a foreign country? OK, here's a contact where I got robbed and almost was kidnapped for organ transplants. I hope you'll like it."
