I do not have an issue with the OP being upset with the quality of work he PAID for, but I truly despise that govt has anything to say about how someone chooses to build something on their own property. As far as getting hurt by tripping over something..... well I still place blame on the person who tripped and not the homeowner. I hate the fact that homeowners can be held accountable for having ice on their sidewalks in the middle of winter or for kids drowning in their pools or getting hurt jumping on a trampoline in the back yard. When I was growing up if I hurt myself at a friends house, I simply went to the ER and our health insurance covered it.... Now, typically the homeowner would get sued due to my error.
Everything now gets blamed on someone else. Spill hot coffee, sue the restaurant. Wreck your car, sue the automaker. Dive into water that is too deep, sue the homeowner. Ski out of bounds and get hurt, sue the ski resort.
The concept of taking personal responsibilty for ones actions is lost in todays society.
