酒 = 氵 + 酉 : The rooster and Maud Younger are downing some baijiu in the outhouse. Maud Younger doesn't notice though that the rooster is hiding a bottle of water behind him and every time when Maud is not looking he replaces his booze with water.

店 = 占 + 广 : Dorothy Gale parachutes into anthill's bathroom. She immediately occupies it (marking the territory with a flag) to open her store.

I can't help but see a bullfrog in 业. Maud Younger finds that the climate in the elevator's bathroom are perfect for her new business: growing bullfrogs.
