When you're playing blackjack, if you're betting $5 and you are dealt a blackjack you should be paid $7.50 (That's 3:2 blackjack).

A few years ago some of the strip casinos started 6:5 blackjack...if you're betting $5 and you are dealt a blackjack they only pay you $6!

Of course, I'm not sure if you can even find $5 blackjack on the strip anymore?
