If it was never used as a congregation point, this wouldnt have started. Go to any other Maccas on a Friday night and do you see riots outside and severe damage to other peoples property.
If people didnt gather there in the first place, this wouldnt have escalated. I went to Maccas carparks years ago when I first got my licence but the out of town ones were all built on retail parks that had a couple of thousand car parks in where 10 cars could sit and chat, causing no bother.
Enthusiasts want to meet, naturally, but do it somewhere else preferably that is closed in the evenings or out of the way so it doesnt encrouch on others enjoyment.
