There is a Dutch chain of baby necessities which is owned by a fundamentalist Christian. You wouldn't know except for the infuriating message their websites (there where some mergers and I think this affects two large online shops) on Sunday, all day long, are closed because of the Sabbath. A multi million Euro business which just shuts down all of its websites on Sunday.

The owner can apparently afford it, because I ran into this when we made a baby and was comparison shopping for a stroller. Obviously you move on and go somewhere else. The owner literally misses sales for his beliefs.

Now I don't want people working Sundays shipping stuff people bought, but those websites can do their thing perfectly without anyone lifting a finger until they come into work on Monday to a stack of orders to handle.
