I did not, but I did FS when I had seriuos doubts and I thougt some householders had pretty good arguments some times, but I could not admit it of course.
And I did FS for a long time after I realized the magazines was very very poor.
I still remember my very last hour from door to door. Geee that was torture, I hatet myself and hoped no one was at home.
Do you remember your last FS hour? And had you realized it was wrong then?
