I understand your frustration as I visited said TA just a few days ago. Bad things happend, but as it was during the week I guess the kids hadn't shown up in force. I saw a number of violations, but it wasn't rampant. Of course, I did get told to go F myself once for trying to explain the rules...
Yep, the TA needs a little Gestapo action. Maybe alittle time limit on how long you can be a member and still go in. Unless of course your an approved Trainer, with a badge and billy stick to back it up.
If you put a time limit on it, I'm sure the tards would migrate to the DA where who knows, maybe they'll learn a little humility.
Hell, I'd even step up for that, say 2-3 hours a week, but only if I had the billy stick. Otherwise it'd just be a journey in frustration.
