Do you think casinos cheat with the game blackjack?

We dont have it all the time it just seems like we do. Next time you go I want you to count how many time your first card is 10 and your next card is nothing. Then count how many times your first card is ten then your next card is 10. After that next time you go do the same for the dealer. It's just more noticable when we have it because we beat the whole table as where when you have it you only beat me :) So I beat 6 people where you beat 1. See what I mean.
