Spotting fake hundos

[chillrob]

If I have a lot of red chips and the dealer is getting short, I don't want to really slow the game down by needing a fill soon, so I will sell someone a stack or two, then immediately hand the dealer the bills and ask for green $25 chips, which they usually have plenty of. Doesn't take any more time, the table won't need a fill soon, and I don't have to have cash on the table which could be fake or stolen when I go to the bathroom.
