I was thinking the same thing.
I haven't done that mistake myself, but I was once talking to someone at the employment bureau and she was holding some brochures I was eager to look at. I held out my hand to receive them. She gave me a puzzled look and then she put the brochures in her left hand and tried to shake my hand. I was only focused on the leaflets so I removed my hand and followed the brochures.
She misunderstood my intent, but it was probably wrong of me to remove my hand. I wasn't dissing her, my focus was only on the brochures I hoped held opportunity for me.
I find shaking hands natural, I have done so in somewhat formal settings since I was 12.
