One thing I should point out too is that etiquette in general has gone down the cack pipe, not just in angling. Having worked as a Ranger for several years I saw the public go from generally reasonable with a smattering of idiots to mainly abusive idiots out for what they can get, with no consideration or care for anyone else or anything present (wildlife, hard landscaping, etc). Infact in my last 6 months as a Ranger we had abuse off almost everyone we spoke to, which kind of made working to create a nice, safe site with lots of wildlife for people to enjoy a bit pointless.
