How would YOU handle this "situation" with a dealer?

[zuluking]

4-8 game. Nice lady is in seat 10. Starting with her button, she raised every hand, 4 straight times, by grabbing 8 chips and saying, "Lets add some sugar.", and tossing them out. On the 5th hand she grabbed only 4 chips to call, the dealer was watching her and said, "What? No sugar this time?", to which the lady kinda went, "Oh!", grabbed 4 more and tossed out 8 again.

What would you do here?

One thing, she had not made a foward motion with the 4 chips when this occured.
