That's a load of crap. If you hired a plumber to fix your toilet and he told you he'd do it in two hours, that's what you'd expect. What if he sat on your couch, discussed your landscaping, and watched TV for those two hours? Then, at the end of his allotted time, declared that he needed more time, continued to bill you, and went out for a beer? Would you accept the fact that no work has been accomplished, he focused on minor issues that don't really matter, he's still billing you, he's STILL not doing any work, and your bathroom is full of s***?
