At first you get caught out without the right ingredients for lunch or wine. Or maybe just want to go get stuff. But after about a year I really came to value this. A day where everyone was off and you couldn't go shopping or get distracted with a bunch of consumer stuff that doesn't matter so much.
I doubt it ever will, but if like to see Sunday or Saturday trading halted again. It's good to have a day off.
The results are mixed. Our highly overworked society only has time for shopping during the weekends, so slashing half of that caused a great deal of chaos.
On the other hand the next day traffic is minimal, so it's a great opportunity to visit friends who live further than public transport can efficiently take you.
It turns out the optimal reliability/cost tradeoff, from the consumers' points of view, isn't necessarily what the entrenched incumbent producers want to provide.
Development is a ratchet, but there's diminishing returns. Eventually costs can seem to outweigh benefits in specific areas.
