i know where you are coming from Kranzy, but personally,i think its just laziness on the staff's behalf, as in too lazy to organise a DOA, or Repair for the product. If i inspect a product that is faulty, and isnt installed by a tech, ill ask to see how it was installed, what it was run off etc, and if the install is good, ill warrant it, no questions asked, but if it is a dodgy install, ill still try to help the customer, but will leave it to the service dept. of the product brand
