Any instructor who spends a good chunk of their working life in the circuit at a small airfield will tell you that this type of stuff is "normal", and that it is almost a surprise to see a correctly performed join or a circuit flown anywhere near the published noise-abatement procedure. A complete lack of contrition from the guy who nearly hit you head-on in the circuit is also standard.
It's pretty depressing really but its hard to see how to fix it when "Captain Average" flies about 20 to 30 hours a year, may have trained decades ago and their only contact with officialdom is a biennial flight with an instructor which has no fixed format, syllabus or standard. I do my bit but you can only cover so much in an hour.
Had a call yesterday from an owner-pilot whose class rating had expired and wanted to reval by test. He wanted to book a date so that he could fly in for it .....
