Yes, really. I have denominated cash chips plainly marked with their values, and still get regs *who have played in my game countless times* sometimes ask what they are worth.
And I see this in other games all the time.
IDGI but it’s true.
Some weird sort of selective blindness, or laziness, where all they see is the base color of the chip… which itself shoukd serve as a tip-off, or ought to be if you’ve played with any set for more than a couple orbits.
