I've argued on the doorstep with an electricity account swapper guy before too. I told him I didn't want to discuss it there and then, and he kept asking me 'why not?'. so I shut the door on him. It was quite scary, to be honest, he was becoming vehement. Lord knows what it's like for little old ladies.

This is one of the benefits of having an entryphone system - with a bit of skill (and luck in having the topmost buzzer) you can generally fend these people off before they gain access to the stair.

Also, how do they tell whose electricity it is? It's all the same wires, and the electrons aren't labelled.

[Raak] You could spin 'em up with a particular bias though. That way you could discriminate yours from the rest by having a filter installed at the customer's service entrance that let through electrons with a penchant for drinking only gravity fed beer or that preferred a lawn mowed in alternating stripes and kept the others out for example.

Don't you realise you're all geing ripped off. It's AC electricity - that means you're getting the same electrons going in and out of your meter day in day out, yet you get charged as if they were all brand spanking new...bloody nerve these leccy suppliers have got, I reckon.
