Cheese or Service?

Amber and Belinda are up on the vat swings above the tanks of mud, they play Cheese or service where Casey calls out a name, and they have to guess if its a service station or brand of cheese… if they get it wrong they get dipped down gradually into the mud tanks, they keep going until one reaches their shoulders and the over head tank of cold mud is released over them… and they dunk their head under… before both come down and get washed off.
