At this time, it happened often, that I asked in a computer shop "I want a notebook running 7 hours on batteries". Salesman: "We do not have something like this". "Okay, than I have to defer my purchase until You can offer me something, I am ready to spent my money".
The most extrem case was a ban to enter the shop as I asked for an energy saving server The company throwing me out of the shop was 3 month later bankrupt.
