OK, Dave(M), at the risk of explaining the obvious:

Your friends who advised you against visiting "a certain club" are entitled to their views. These things being subjective, there will always be someone who might disagree with them. You are of course within your rights to trust their opinion and not visit that club.

But as I said, these things are subjective. I have views about some clubs too. I would never dream of airing them in public however, as I don't want to risk potentially slandering a club based simply on my own subjective views. And so I declined the invitation to state my "worst club", initially in a roundabout way, just to be polite.

And I hope others will, too (decline, that is). But that is for them to decide.
