A) Carl possibly smokes to much you know what.
B) He's never been somewhere like China (where I've had my bag raided for anti -regime literature on arrival!)
C) Most likely is a petty thief that thinks he should get free energy.
If you want to calibrate your smart meter then simply do the math! It is not that hard for anyone with an education Carl....sorry what am I saying?
Wasn't Carl the one that had his door kicked in and a pre payment meter fitted ?? Don't know what he's so worried about, I don't think they'll be fitting a smart meter to his any time soon !!
