Given that you are not content to keep your head down and see what the lie of the land is on Monday morning, personally I would simply ask my manger on Monday if I could have a copy. To start with. This is proportionate and will probably get you what you want. To go weighing in "all guns blazing" with a SAR seems over the top for what I read in the other thread(s). And may guarantee a defensive (and as a result hostile) response.

Frankly your over blown response to this leads me to believe you may have been very rude to the security guard. Think about how your action in one situation may infer what you did in another. You currently present as someone with no sense of proportion. Also who cares if another site's users want to pop by? It's the internet. People move around it.

Quite right; it's not slander, although it wasn't you I asked the question of, but your super-loyal customer Mr Baron, who appears to have registered on CAG only in order to post a couple of ill-informed, semi-literate, frothing rants which include references to slander. It will probably be helpful to clarify a couple of points. Slander is spoken. Libel is published. Both are forms of defamation. If someone brings an action for defamation, firstly they need very deep pockets - it is one of the most expensive forms of litigation there is, and most defamation lawyers will want an upfront fee of tens of thousands. Secondly, you will have to show that the defamation caused a harm - demonstrable loss of business, for example, or the defamation causes a right thinking person to think the worse. Truth is an absolute defence, so is public interest. The law was recently strengthened to prevent companies and individuals using it to suppress criticism. In other words, you may not like what some of your customers are saying, but you are probably not really going to be able to do anything about it, especially in a 'he said, she said' situation. I suspect that no-one, and particularly a used car dealer, is able to please every single customer every single time - especially as there are customers who will never be happy no matter what you do. Meanwhile, you may like to read up on the Streisand Effect - for an example google 'RLP Schillings'. Let's have no more silly threats about slander.
