Chuck Norris is in charge, and if you do skids or make a d*ck of yourself in the car park he will end you.
Naah man we are welcome there, we buy ice cream and just hang out and catch up. The owner seems to like us coming, we get discount (anywhere from 10-60% depending on who's working and how lucky you are).
The only time we ever had any trouble was one week when a bunch of w*nkers turned up, reved the sh*t out of their boostlosing mobiles and did skids, and generally made d*cks of themselves in the car park. The surrounding businesses called the cops and hired a private security guard, we had to relocate temporarily untill the dust settled.
Those people are no longer welcome, and anyone else who behaves in a similar manner is also unwelcome.
Everyone else is welcome
It's also polite to buy ice cream since we take up most of their table space all night . As mentioned above, we get discount
