A Macedonian man left his wife at an Italian service station and only realized he had driven off without her six hours later, news agency Ansa said.
The couple, who were travelling with their 4-year-old daughter, pulled over for petrol in the coastal city of Pesaro as they were heading back to their home to Germany.
After filling the tank, the husband drove away -- without noticing that his 30-year-old wife, originally from Georgia, had got out of the car to go to the toilet.
The woman, who had no money or documents with her, contacted the police who eventually traced her husband to Milan, some 340 km (210 miles) north of Pesaro, Ansa said.
The husband told police he had not missed his wife because she always sat in the back of the car with their daughter.
