Just heard a funny story on the radio ...Some gasworks were going on in this blokes rd and for whatever reason his garden was dug up and he asked them if his house could be piped to have free gas.The Engingers replied no problem and when they had finished low and behold! Free gas..!But after a while the gas went off and nothing worked, he thought well I can't exactly call BG as I'm stealing this gas so he proceed to dig his garden back up to see what was going on...He followed his gas run under the garden and found it connected to a buried gas bottle.l
