Absolutely exhausted. Walked around a bit, combining Google Maps with commonsense wandering to secure enough food for the next few meals, which is no mean feat in an ex-Yugoslav city on a Sunday night. Between a few convenience stores and a late-night fried-things bakery that sold bread as well, sufficient grub secured, at around half the cost of a couple meals sourced from a proper grocery.
Very strong contrast, not only with the average American city (which, in fairness would me much less walkable) but also with the more Western countries to the east and the north. It's basically the same logic as going to Wal-Mart all the time when I was working in outdoor dramas in Kentucky -- going to the distant places is much easier when you can handle support and supply issues quickly and efficiently. The German hypermarkets were my base in the country to the east -- even in the largest cities. When the means of securing necessities are clear and direct, the complexity can shift to where it's more profitable -- the thinking, the making, the reading, the exploring, etc.
