Supposedly, this filthy showerhead can be found in a 4-star hotel. Well, they need to remove at least one of those stars until the hotel staff has given the place a proper clean because this isn't worthy of a $20 motel room, let alone a resort. Guests who stay in the best hotels always reference attention to detail as what sets them apart from other places — this is the opposite of that.
No hotel guest should feel the need to take another shower immediately after having one, but it's pretty likely that plenty of guests here have felt exactly that.
