.. Then you ask them to drive on. and they do, but stop just short of the road, so they still block the exit. You then have to go outside and tell them to get the heck out of here..
And then you will have to call the cops, only to have them arrive 2 minutes after they drove off. And you are left with a long line of angry customers.
My advice, buy a air horn, if you annoy those people who won’t drive true enough, they won’t come back..
