A good public bathroom is a rarity in the city. When you find one, you will treasure it, and pay any price to continue using it. Shopkeepers know this, so signs like the one above are commonplace. Trust us when we tell you that the cost of a croissant or an apple turnover is a small price to pay for a tidy restroom, no matter how much pastry-for-privacy extortion may offend you. Another sad truth is that no matter how much you hate the over-priced faux-culture of Starbucks, you will spend a ridiculous amount of time there while you live in the city, as they offer the only reliable, free public bathrooms known to mankind. Not to mention the free WiFi.
