Desire To Install Tinted Windows

Mr LL called my master again this afternoon. I was at the showroom, and Mr LL wanted my master to give him advanced payment (in full) for the Llumar tinted windows film and the security Captor RF system.
My master argued that my windows already looked dark and no need to install tinted films except at my back. However, Mr LL told him that the LLumar tinted films are very special product, because they are hard to break into.
My master came to the showroom to look at me before I was sent for inspection to Custom in Port Klang tomorrow morning.
