As said before if people were driving there for a 6am meet, then that could be disruptive to local residents and RBWM and Lee need to work together to deal with it, but it sounds like a resentful former owner and his sidekick from the start, who just happen to be a RBWM councillors, and the whole thing has been dealt with disproportionately and in a rushed way by the Council.
I do wonder as well whether this is a bit of a Boxhill syndrome of disgruntled local residents who dont like being held up by the increased number of peletons on the local lanes, finding a way to express frustration. I am very local to the Cafe and see them quite regularly, but its nice to see so doesn't bother me*. Ironic that this issue has lead to far more club runs to the Cafe to show support.
*Although the groups dont help themselves at times as I have seen some terrible standards of cycling. Its not difficult to pull over and let cars past if you have a queue of 10-15 cars behind you? And when you do stop, why not indicate and pull over just like any other road user, rather than just stopping in the middle of the road?
