You see enough at B&M like, rubbing the coins/notes because they have to be warm for the machine to pay (can;t put anything cold inside her), rubbing the screen like its your last night together, giving the old girl a tap on the backside and saying "there there girl" it about time you put out.
Then there's the getting angry at the machine like its meant to give you money like an ATM/Bank Machine and punching it or slamming the buttons seems to work wonders for some people.
Gamblers.. pffft
Seeing people doing that is always funny... People rubbing the screen, touching the screen, patting the side of the machine lol! I've been playing for a while and still don't do any of that... What good is rubbing the screen gonna do? May as well hang a lucky rabbit foot on the machine.
As for me well... I move around constantly, I seem to do better like that and also enjoy being able to play more games
Sometimes I'll make faces when I'm about to get a close win. So close yet so far
