So what did you do, Lordy, just watch? Or report the incident to the site managers? I've never witnessed bad behaviour on that scale, but I have seen site managers intervene very quickly when rules were being infringed - ball games or cyclying between units for example. Nor have we ever noticed that 'tenters' behaved in a way that was any less responsible than 'caravanners'; in fact, many people have both tent and caravan and even more caravanners started out in tents.
We have never felt that we have been directed to a pitch on a C&CC site: usually, when we arrive, we are asked what sort of pitch we want - in the shade/in the open, near the toilet block/playground, etc. We have often been shown a map of the site to help with our choice. After that, we have been shown to a pitch, but if for any reason we do not think it suitable, an alternative can almost always be suggested. Where is the problem with that?
We do, as a matter of fact, find many Caravan Club sites rather carpark-like. The hardstandings themselves are part of this, but also, of course, the need to pitch on a precise spot, parallel to the next outfit, which follows from having hard-standings, exagerates this impression. It is purely personal preference, but it doesn't provide the sort of ambience in which I can really relax.
