Sign spotted at a 7-11 recently.

Saw this sign posted on the front of a busy 7-11 recently...

I hadn't seen any signage like this on other rural 7-11 stores, but this one is on a busy road from Numazu to Fuji Speedway. There must have been a lot complaints from the neighbors about people with modified cars, in race mode, rumbling through on their way to and from the track disturbing the peace.
