I just had the same thing happen. A lady had purchased some lotto tickets,came out to her vehicle and proceeded to set there and scratch off her tickets, while I am obviously waiting behind her. She finally exited the vehicle again to go in and purchase some more tickets. Came out and did the same thing. Totally oblivious or does not give a hoot. I don't know which. She looked like a freak. I pulled up against her bumper and laid on the horns. Did not phase her at all. Altogether since I could not back out, I waited over 20 minutes on her to eventually pull off and give me the finger. We have got to clean up that gene pool.
