I've had an occasional problem here in the Phoenix area, with leaving my helmet on when entering to pay for fuel, but this was usually in the area of 1-4 am, after coming home from work,
I can understand it at that time of day, but not all of the time, unless there is a problem of not paying for their, purchase and leaving.
Maybe there's cameras and they can't get a good picture of the offenders.
It will be interesting to see what brought this about .
