I agree that Sri Computer has really rude staff...
I went to LYP to get a low-end (400+-) graphics card for my uncle's PC, and I approached the Sri Computer staff. Asked a thing, he acted as if he did not listen, reasked, answered abruptly and shortly, as if not wanting me there. Then I asked other things and he just answered dunno and went chatting happily with his colleague, ignoring my presence sitting in front of their sales desk. Very very bad customer service and totally no respect for me.
Immediately went off and bought a graphics card at another shop.
