Dutch stores close on Sundays. Grocery stores, clothing stores, drug stores, bakeries. Almost everything, at least in small towns like ours. So if you find yourself in urgent need of something unexpected, say something related to feminine hygiene perhaps, you'd better get in the car and find yourself a gas station that sells more than soda and chips. If you're lucky, there will be one large enough to sell tampons. And chocolate to make you feel better.
