Factual error: After Mike sets Worm up at the club and leaves, Worm asks for $2,000 of debt in Mike's name to sit at what was moments before identified as a $20/$40 limit game. The woman is next seen putting four rows of green $25 chips into a chip rack. A $20/$40 game would never be played with $25 chips because this denomination makes it very difficult or impossible to bet the required amount, at least without $5 chips to make change on every bet, which would be extremely tedious. Rather, $20/$40 games are played with $20 chips made specifically for games of those stakes, and they are usually yellow in color.
Suggested correction: Maybe they don't have any of those left. In that case he could play with those.
