No but I know if you get overcharged they will reimburse you so it go's both ways.I sometimes work with the electrical boys and have heard some wild stories about gas and power meters.The new digital ones are pretty accurate but the old style were not very consistent and prone to faults and tampering.
Heres a story I heard 2 days ago. Back around 1960 an old fellow walks into the calgary power office and says he wants to get on the 24 hour plan for his power.There is no such plan so they went to his bachelour pad to see what he was talking about.Seems the old fellow had had his house wired from the city street light for 20 years and as he only had 2 light bulbs,they allways worked.It was when he bought a tv that he noticed he had no power during the day when the streetlights went off.So he thought he was on a 12 hour plan.
Heh! they had to pay him back a whole bunch of money as back then there was a minimum charge no matter how much power you used.
