live blackjack dealer exposed card by mistake and round got cancelled after i won.

i get that they have to follow the rules when a dealer messes up, but man, it stings when you actually win the hand and then suddenly it’s all off. i had something similar in roulette once, like they spun while someone was still placing chips and called it a no spin. i guess it’s supposed to keep things fair, but it always feels suspicious when your luck’s finally good and they just wipe it away.

do you think this is just about them making sure no one takes advantage, or is it more about covering themselves so they can’t get accused of helping someone? i start doubting a bit whenever it happens, especially if it’s a big bet. does anyone have experience where a dealer exposed a card but they still paid out the win, or is it always just automatic cancel?
