Way back when, when my instructor cleared me for my first solo flight, they told me to make three touch-and-go landings. So, ever the dutiful student, I requested three touch-and-goes from the tower.
Of course the tower, expecting the usual full stop landing the third time around for a first solo, was wondering why I was back in the air after the third one, and cleared me for a full stop (when I asked for it) the fourth time around...
