Chapter 11: The Heiress - S2-E3
Other mistake: Mando's ship is completely devastated, gaping holes in the hull, patched up fuel lines, engines malfunctioning, and on top of that entirely flooded. The Mon Calamari repairs it for 1,000 credits and the protagonist acts like he's been ripped off. When Mando in season 1 turned down the bounty for the guy who missed bail, Greef Karga offered him 5,000 and Mando replied that it does not even cover fuel. As exaggerated as it could have been as a statement (he was complaining and perhaps haggling a bit), and as bad as the repairs prove to be, 1,000 sounds disproportionately small for repairs on massive structural damage AND refuel.
