The most unwelcoming clubs that I have been to purely as a punter have been open to customers "off the street". The funny thing is that they are the ones that the guitar jockeys here praise to the skys.

As a non performing punter by far the rudest club I have been to was Maidenhead. The total contempt for a paying customer was mind boggling. Their loss - a couple of hundred pounds in entrance fees that have been spent elsewhere over the years.
