whats wrong with them opening a cafe?
theres already one there, but its hidden away.
personally when i went i thought a shop selling drinks would have been handy. i know theres a pub there, but i dont go to pubs and i dont drink alcohol so i wouldnt have gone in there.
its not like they have taken it over and put avebury world signs all over the place.
its still pretty open and free from tacky signs or money making things.
and as long as they arnt building a new building there, whats the harm?
