blackjack table changed rules from h17 to s17 after refresh or maybe im blind

just noticed something weird at the tables last night - swear i sat down at a blackjack game showing h17, played a few hands, took a bathroom break, came back after a refresh, now it’s s17. maybe i’m just tired but i’m pretty sure it switched mid-session. anyone else ever see that happen? i’m not talking about hopping tables either, was the same seat, same dealer.

if it did change, what’s the point? s17 is better for us, right? can’t figure out if i got lucky, missed something obvious, or if these places just swap things around to mess with regulars. i mean, i try to pay attention to the little rule cards but sometimes they’re kinda hidden or quick to flip screens. have any of you seen the house edge rules shift like this before, or is it just me missing it?
