re: Has this situation like this ever happened to you while waiting in line at a store?

Yesterday I was walking into the doctor. A lady was behind me in the parking garage. I held the door open for her. She politely said thank you. Then walked ahead of me. We get to the office door, she didn't even look back, slow the door down, or consider returning the favor. Of course she got ahead of me to check in. Check in normally takes 20 seconds. She took 5 minutes.
