why are live dealer tables always full during peak times

i'm noticing this more and more - every time i try to sit at a live blackjack or roulette table after work, every single seat is always taken. like clockwork, just when i think i'll sneak in a few hands before dinner, it's packed out. doesn't matter which site i try, peak hours are just slammed. i get that the vibe is better with a live dealer but i'm wondering, is there just not enough supply or is the demand way higher than it used to be?

feels like they should add more tables, but maybe there's some strategy for keeping things limited to make each seat more "valuable" or something? i like steady play so bouncing around waiting for seats isn't ideal for me. any regulars notice this getting worse, or is it just me? how do you usually find an open spot when it's busy?
