Lol I am a "beginner" if you call, lbut a lot of peope underestimate a lot of kids (like me, im only 18). I get stupid looks all the time when I sit down with $200-400. Most teens are there to just have a good time, and not to become card counting sharks.
With that still said, it truely does piss me off when people do horrible moves. I was at a table. I was at first base, and there was 2 other. Dealer was showing a 10, the guy next to me splits 10 3 TIMES!!!!!! Guy next to him stays, dealer flips a 2, then 9. We all would have won if it wasnt for that idiot (I could tell he had no idea what he was doing).
This is the reason why I always go in the early mornings to the casino. I don't go for fun, If I go its for some serious business. I can usually get a table with one other person, sometimes all alone at the minimum tables.
