"Well, one of the greatest misunderstandings about electronic locks is that they would fail in a power outage. This is simply not true. Each lock would operate on a battery until such time that the power was restored."
I nodded my head at his answer. Ten points for professionalism, and another ten points for what I said going right over his head.
"And if there is a power surge that fried all of the electronic components?" I asked, a fake smile on my face.
"The chances of something like that happening are less that 0.05%," replied Liu Ming Jie, the look on his face suggesting that he was talking to a paranoid child.
The joke was on him; I was neither paranoid nor a child. But he would learn the hard way.
