All concrete cracks.

Good concrete, properly installed, doesn't crack. If that's so rare as
to be moot, then fine. But expecting cracks is lowering your
expectations to that of the ignorant and apathetic masses.

I recently looked at a house for sale, with a very large concrete patio.
IIRC the house was built in the 1940s or so. There isn't one crack in
the patio. Not one. Not even a tiny, hairline crack, anywhere.
