Waving someone's hand away and saying there is no such thing as luck is kind of rude. Shaking hands is a traditional sign of respect before the starts and is actually part of the international rules.
I do find the phrase "good luck" to be somewhat strange. Does anybody here actually wish good luck for their opponent? I always say "good game" instead of "good luck".
For this very reason, I have gotten into the habit of saying either "Play well" or "Have a good game" when I offer to shake the hand of my opponent. There are those who refuse to acknowledge even this, so don't be surprised by this slight. It helps to remember that manners don't count OTB, and there is no "rule" to ban bad behaviour. After all, you can't legislate morality, decency, or common sense so if someone is deficient in one or all of these traits don't take it personal. It's them, no you.

One time at a tournament there was a problem with the pairing system so the computer said that I was playing in the first round against 5 other people.
They all stacked on top of each other in the same chair and became fused. I applied a varnish and sold that totem pole on ebay for $215.00.
The cost of the varnish was $10 so the profit margin was quite good.
This story is not true! That quantity of varnish would cost at least $15!
