Query: Working at the Car Wash!,

Enjoy your very own hair follicles and sputum within the confines of your own home. Tired of using other spas which have grease marks and strange substances floating within them? Well then, try this portable spa! Fits right inside your living room and all it needs is 900 gallons of water. Be careful with needles and sharp objects and do not use around electrical appliances or battery operated hand-saws.
