long island car wash

this is what the tip cup looks like at the car wash I frequent. it actually is held together with duct tape. all the guys and gals that work there work very hard making my car clean and shiny and fresh smelling. they will never accept a tip unless it is put inside this box. at the end of the day they share what is in the box equally among them. this is how the people behave on long island.
is car wash one word?
