I see no problem in having a 'one-price-fits-all' for zoos (and for other things such as public transport, cinema tickets etc). What annoys me is when somewhere has child and adult prices separate, but charges somebody who is legally a child as an adult. People aren't adults until they are 18 (or is it 21), so I don't know where zoos, cinemas, buses, trains etc got the idea it was between 11-16![]()
Yeah, but how many of those 16 and 17 year olds want/try to get in pubs, clubs and cinema under-age -you can't have it all ways all the time
Basically, we're all happy when we're getting a bargain and we all whine when we feel others are getting a bargain and we're not (me included, it's human nature) -life's not fair, but in the UK it ain't too bad in the big (world) scheme of things.
As I've said before, entrance charges (zoos and otherwise) is all down to economics. The marketing people's job is to try to pitch price structures to maximise their revenues (which all zoogoers, and supported conservation programmes, ultimately benefit from).
For anyone vaguely knowledgable of economics the pricing structures are based around using discriminating monopolies to exploit differing elasticities of demand (no, come back/wake up it's really interesting.......).
