Usability, or the general lack thereof, kills me. I went to the gas station. The pump I pulled up to had a tiny note on it when I went to put in my credit card that said basically: broken, move to another pump, or pay inside. So I go inside and say I want to fill it up on my credit card - which I can do when the pump reader is not broken - but the person in the store said oh no you either have to give me a specific $ figure, or move to another pump.

So I told him I'd never give them my business ever again and drove away. Man.
