Sauna to cold plunge

Why do people leave the sauna and jump straight into the cold plunge without rinsing off their sweat first? Are they just unaware, inconsiderate, or oblivious? Speaking of which, the layout at Domino's location is terrible. There's minimal thought given to the flow of people, and there are no hooks for towels. Someone should be held accountable for this poor design. I could go on and on.
