Parkruns are lovely except in Woodlands

We have recently joined the Parkrun society in the Gauteng area and rotate our 5km Parkruns each week. The experience has been lovely with a friendly, jovial and social atmosphere at all venues except Woodlands. There seems to be a core team of runners that frequent that specific area and think it appropriate to scream at runners who are in their way (quite easily achieved given the route laps back on itself before the end) and are exceptionally to rude to people who make honest mistakes route mistakes along the way.
