why do live dealers sometimes flirt with players to encourage bigger bets

so i've been playing a ton of live blackjack lately and noticed some dealers get real flirty when the bets start getting bigger. like, actual winks or calling you lucky or sweet-talking with compliments. i get the job is to keep people engaged but sometimes it feels like they're trying to hype you up to push bigger chips. i’m just curious if this is like a tactic they get trained on or if some dealers just decide to do it cause it works for them? or maybe the casinos push this so people tilt or chase more.

i don’t hate it or anything, it's just weirdly obvious at times, especially during late-night sessions. feels a bit like a slots bonus round where everything flashes and makes noise to make you click. i wonder if anyone’s noticed any difference in their own betting when the dealer gets all charming like that? do you play along or does it throw you off your rhythm?
