Free Power
While moving into a new place is always exciting, having to pay bills seldom is. When this person got the keys to their apartment, he realized that he had to transfer the electric services to his name. He went to the company like a good citizen but was told that they only had records of 7 flats in the building while his flat was number 8.
He was asked to come back with the serial number on the meter but the OP figured that this was a golden opportunity that he should take full advantage of. He ended up enjoying free electricity for over 2 years before he finally moved out. Some people have all the luck, huh?
