Luckily I never met salesman with that kind of attitude in Senheng/SenQ over here. In fact, they are all very friendly except that they might not very clear on some of the equipments spec. I can understand that it's not quite possible for them to know everything inside out. So everytime before I go shopping, I will do my research and study first. Then baru go over to touch the item, if they have it in store.

Cheers!
