Two cranky customers at a Downtown Brooklyn IHOP flipped out like a couple of flapjacks and got arrested after they tried to skip out on their bill, authorities said yesterday.

Tashanna Davis, 23, and Virginia Monger, 22, allegedly scarfed down a smorgasbord of breakfast at the pancake house at 276 Livingston St. at 6:25 a.m. Saturday.

After they were hit with a $46.85 bill, they tried to pay it with just $30, and complained the service wasn’t up to snuff, sources said.

Both women were charged with theft of services while Monger was also slapped with resisting arrest and attempted assault.
