I used to work doing stuco in east Texas. One guy just never paid us, so we spent a day tearing down everything we worked on.
Another time, while working for a small machine shop, a customer kept d*cking us around about paying for some work we did. Was all a walk-in job. Paid half up front and would pay the rest at pick up. Well, he needed his part NOW and would pay us the remainder in a month or so. So....... We cut his part in half and said we'll give him the other half in a month or so.
Lesson of the story, don't f**k around with contractors.
