Dealer scan delay?

been playing live dealer games more and noticed sometimes there's like this awkward pause after the dealer scans the cards, especially on blackjack. sometimes it feels instant, but other times you see them waving the card in front of the scanner like it's not reading or something. usually not a big deal but when i'm on a streak or need that last card to hit, it gets kinda annoying.

not saying anything shady is going on, just wondering if anyone else is seeing this and if it actually means anything for the game. patience is my thing but sometimes those pauses make me wonder if it messes with the rhythm or if the dealer is just having tech trouble. want to see if anyone tracks or cares about these delays too, or if i'm overthinking like usual.
