This is so true, I've come across a lot of weirdos that think a butterfly farting in Singapore might affect their play in Las Vegas. ...hmm, maybe it actually might... ha!
Superstitions are a funny thing and gamblers are wired differently.
My peeve is I have a choice of two machines, I pick one, start playing, then think I picked the wrong one, then someone else sits down at the alternate choice and within a few hands (VP) or pulls (slots) they hit quads or a bonus round while my machine is sucking my bankroll dry. Happens more often than not. I'm sure if I sat at the other machine the same would happen as well! But its an RNG thing versus sitting at a lucky machine.
