Correct me if I'm wrong but has driving courtesy gone out the god damned window?

The other day my wife and I were about to pick up some cheap drive thru bag and go for the kids. We went to one of the local Jack in the Box's at a Safeway super mall. This particular J in the B is located at the far end of the lot, putting it between the main drag and an open pile of parking stalls. The store lots nearby are vacant so their isn't much parking there. To better paint the picture: there's several hundred feet of open space around the restaurant. The main drag runs parallel on the north side of the Box and an imitation road, the kind they set up in parking lots so people don't drive through the stalls runs parallel with the south side. Now, to get to the drive through you have to enter a short drive at the east end of the Box and it only allows room for two cars before it turns around to the drive-up window. There are two menus for the first two cars to preview there so if you're third in line you can either block the imitation road or wait on the other side fifteen away from the drive through.

Being the civilized people that we are, we waited fifteen away in broad daylight in our dark blue Chevy Venture mini van (hey, I got four kids and they don't fit in the Cavalair anymore). As the person in front of us checked the menu and the person in front of them ordered, some teenaged twit with her cellphone glued to her face whipped in front of us and blocked the drive. Then to add insult to injury, some old fart dying for a heart attack looked at us as he pulled in behind her. Now as I stare at these two lame brains I'm thinking how legal it would be to walk over and smash their windshields. As they scream at me I would reply, "Oh, I didn't see your car there. My bad." Screw common courtesy and fast food! I'll stick to PB and J just to avoid these idiots for the rest of my life.
