Bonuses are not for free. If you see the terms of using the bonuses you'll see something like: you have to play 1000 times the amount of bonus in order to get it. So it's not as free as it seems.
And of course this couldn't be happened technicaly at live casinos, for 2 reasons:
First, because for each one player who uses bonus, the dealer or someone else should keep tracking the size of bets in order to know each time what money has spend until he reaches the term of bonus and second even if casinos used so many additional stuff for this job, guess how many hours or days the player should sit continuslly on the table to use 1000 times the bonus.....!!!
