How safe is it, really?

I don't know why more pilots don't do this.

I don't know what you are flying, but with the planes I fly, full
tanks aren't an option unless I want to fly alone.

It should be obvious that I wasn't suggesting that anyone overload
their aircraft.

No, but you were wondering why more pilots don't "ALWAYS refuel after
every flight, so that [they] always have full tanks," which is a silly
practice unless one ALWAYS knows the next flight will require full
tanks. At my old club, members were asked NOT to fill the tanks after
using the airplanes, so that the next pilot could add fuel appropriate
to his flight.
