Put it this way Dave , I am a part of the Zoo world , albeit not in this country (where I am currently located) and the comment was said very much tongue in cheek

.
As such , I'm well aware of the zoonosis / pathogen transmission risks , health and safety legislation, and of course stress and behavioural responses in animals to visitors in Zoos because part of my work back home is mitigating this behaviour in visitors and ensuring our animals welfare conditions. Needless to say , I wouldn't be stupid enough to just go absent mindedly wandering through corridors that are sign posted as "No Entry"

or "Private".
Ultimately , I suppose its quite good that someone at ZSL is actually bothering to read posts on the forum. Perhaps you might kindly direct their attention and that of their superiors to all the constructive criticism of the zoo that zoochatters ( Afterall visitors hard earned cash goes to funding their In-situ and Ex-situ conservation programes , does it not ? ) have posted over a span of several years ?
ZSL are certainly in better straits financially and have far better funding then our institution back home and far less excuse (None whatsoever as far as I can see) for all the cock-ups , hollow platitudes , reports by ex workers of a toxic organizational culture and bureaucratic mismanagement.
Furthermore, I understand your role as moderator on this site and in trying to maintain a constructive relationship between this community and zoos but I'd rather you took it easy on Pipaluk. He/she was evidently not trying to encourage trespassing and was simply stating that the enclosure could be seen from a number of vantage points in the Clore building , a structure that is characteristically (for ZSL) eccentric and confusingly laid out.
