Sun coming out but camera on wrong setting

Yesterday afternoon we ate supper at our favourite no-meat restaurant.
We're not vegetarians most of the time but we like the food at
vegetarian restaurants. This was the view, at sunset after the rain
and snow let up, of the restaurant's plants in the window, and the
sun-lit buildings outside.

I accidentally had the camera set at 1/4000th instead of at the A I
thought it was at. It's an accidental setting I'm getting used to
with this camera. The shutter-speed wheel turns when the camera is
going in and coming out of the pocket. And usually I'm not bright
enough to notice until later. I had to jack up the light levels a lot
to get this.

But, as so often, I rather like the effect.
