"This typically means that a Casino Manager does not like an $8 chip as it complicates the work process of the dealers. Which can lead to errors or the slowing down of play."
Not true, IMO.

$8 chips are not even in the program to order fills.
Dealer takes it, changes it for $5 and 3 $1 chips, and drops the $8.
No different than accepting any foreigh chip.
