#16: Confusion Over Paid Public Toilets
Few travel surprises feel more urgent than finding a coin-operated gate between yourself and the restroom. Americans generally expect public toilets to be free inside restaurants, department stores, museums, and transportation facilities. Across parts of Europe, particularly in railway stations, motorway service areas, and heavily visited city centers, a small charge is still common. The fee helps pay for cleaning, toilet paper, repairs, attendants, and security, which is why some paid facilities are better maintained than free ones nearby.
