does sitting out too many live blackjack hands make the casino flag bonus play

If I’m grinding a welcome bonus at live blackjack, I usually want to avoid doing anything that makes my action look strange to the pit or risk team. Thing is, if I just sit and watch too many hands or barely play while waiting for good counts, will the casino see that as a red flag? I’m not talking about card counting to the extreme but more like hanging back on some bad hands and getting in on the better ones.

Feels like sitting out too much could be an easy way for them to spot someone not playing “normally.” At the same time, I’m not about to throw money at the house just to look like a total fish. Does anyone here have firsthand stories or insights about how much is too much when it comes to sitting out hands during bonus wagering? Am I just being paranoid or is this something casinos actually track closely for live dealer promos?
