If I would be in charge of tourism for a city I would spend as much money as possible to make the restrooms of the local airport as nice as possible. Sitting in a A330 waiting to take off to Amsterdam, the restroom is pretty much all I remember from Memphis. Those 15 minutes I had on the ground could have been better used to the advantage of the town.
Speaking of travel restrooms: On the first leg the flight attendants had put a bag of coffee on the coat hanger in the bath room. The smell of the room was better than usual. Funny how those bags are usually not more than 5 feet away from the bath room. But it took years before some smart flight attendant had that idea. It was probably that cute deadhead sitting one row behind me.
