I think you were right the first time... This business was happy to have and promoted gang business. The police thought so and closed them down. The home company has revoked their franchise. That’s enough for me...
You can retract promoted but in actually, they allowed and encouraged participation it seems to me...
So, no you did not use an improper term...
A little FYI - there were “Biker Nights” held somewhat regularly at that Twin Peaks, which of course attracted the gangs and made them feel comfortable about being around there. Well, the same bozo who had the franchise in Waco ALSO has the Twin Peaks franchise in Harker Heights near Killeen in Bell county, just south of Waco. Biker Nights are now cancelled at that location. Somebody needs to really look into that dude, he's sounding shady and was probably presiding over some extra curricular activity at those restaurants. Saw that he hired a PR firm - which doesn’t return phone calls - and they released some slippery multi part weasel-worded statement. Corporate headquarters has washed their hands of the Waco location to put the stink on him, getting ahead of the curve from the civil lawsuits that are about to go flying.
