Dealer mistake ruling?

Last night at the table, the dealer totally miscounted the value on my hand and tried to pay me out on a bust. I started overthinking if I was missing something and nearly let it slide, but caught it after like two seconds of sweating. Pit boss fixed it right away but it made me realize how easy it is to mess up when your brain’s been counting chips and splitting tens for hours. Never trusted my own recall less.

Anyone here ever been on the receiving end of a dealer mistake that either cost or saved you? I feel like my ego always wants to believe I'm the sharpest one there, but I know that's exactly how I end up getting fleeced.
