If your job is small and simple, you'll probably be ok with Raffi, if instead it's big, forget about it: He will create the same imperfections over and over again, hoping that you won't notice He will pretend not to understand what mistakes you ask him to correct, hoping that you'll get tired of asking He will tell you that lower or higher areas don't need to be properly finished because you normally won't look at them He will tell you that not all surfaces need to be smoothly finished, because you won't touch them all the time He will tell his employees to rush the job in order to get finished, to the detriment of quality He will pretend that something can't be done even though he previously already did it He will come up with fake technical explanations to justify his shortcomings and when you prove to him he's lying, he'll hang up the phone or leave the job site He will keep asking you to be paid more for the same job, and even after you agree and pay him more, he won't complete the job and will eventually vanish He will ask you to be paid cash
