anyone notice live dealer outcomes change when more players join

I've been at the live blackjack tables and swear the flow of the game shifts when a few more folks jump in. Sometimes, I'll be running decently heads up, then a couple new players slide in and suddenly dealer’s getting way more twenty-ones. Is it just variance working overtime, or does the deck get clumped differently with more hands in play? I know card distribution shouldn't care who's there, but it genuinely feels like the shoe heats up or cools off depending on table count. Probably just superstition, but it's messing with my head a bit.

Anyone else sense this, or is my snack drawer making me paranoid again? Do you stick around when more join, or bounce and find a new table?
