I did a job for a friend at church early in the summer. Was supposed to mow his mother-in-law's house on hickory street , but instead mowed the one on hickory place. Oh well the guy that was living there showed up and gave me what i would have charged anyway cuz he was moving out that day and now he didn't have to mow. On a greater scale there's a hotel in Branson Missouri that the front faces a rock cliff because i understand that the guys who poured the foundation set the forms backwards. Rather than tear it all out the just built it facing the cliff.
