Dealer signature real?

dealer signature feels like one of those things you either totally believe in or roll your eyes at. i started watching for it after this dude at my local kept winning on what looked like the same 2 sections of the wheel. i can’t decide if he’s just lucky or actually reading something the rest of us aren’t catching. i’m always thinking, maybe there’s something to this, but also roulette’s meant to be random, right? i keep a notepad with numbers and wheel hits, but after a while patterns seem to show up and then vanish again, like it’s just variance teasing me.

anyone actually tracking spins and feeling like they can read a dealer? or is that just the receipts talking and i’m better off focusing on my slot bonus rounds?
