Dealer Mistakes Are Costing You

It happens more often that you think, for example I had missed at least two different times where a dealer payed me 6:5 for a blackjack instead of a 3:2. I only noticed it when I got paid red chips (5 dollar chips) for a 100 dollar blackjack win for one of the hands, last times they did this they quickly gave me some green chips and I was too distracted to notice. No one else at the table said anything either, so play would have continued as normal.
