you know where she lives, send her a rude letter, or post her a poo or soemthing

better still,break her windscreen so that she needs another new one, that way you can go out and find her and call her a twat to her face

or you can look at it in a grown up manner (unlike her) and just take it as part of the whole bmw owner sterotype, and seeing as she doesn't actually drive a bmw, she's got idea's above her station and nothing you say will placate her

move on and forget about it, i know it's not going to help your record but what a you do? nothing, so don't worry about it and just carry on despising them twats for that very reason

as for the rest of you, i can understand if it's a bit of sticky that will come off, but what if it tears?
it's not as if it's going to be glued back on again is it/
and what do you do with them secutiry tamperproof holders that you can't get off without tearing the tax disc?
