best blackjack for actually understanding when casino heat starts

so i keep seeing talk about “casino heat” and getting watched at the tables, but honestly i feel like half the time i can’t even tell if anyone cares what i’m doing. i play almost all my hands at live dealer tables online but sometimes i get to squeeze in a real brick & mortar session if i’m near one of the river casinos. when i do, i always worry i’m overthinking it. like, is anyone actually watching that close if you aren’t betting huge or pulling wild spreads? the pit bosses mostly just hover, chatting or pretending to look busy.

it’s confusing figuring out what triggers that real casino heat for blackjack players. i mean, you always hear stories, but is it always about bet spread or do they watch for things like play deviations or just sticking too close to the math? i’m not into super aggressive moves - just like being careful, picking my spots, not rushing. if i get up and leave after a win streak, do you think that actually raises eyebrows, or do you think everyone’s just too busy to care unless you stand out way more?
