One time I had a late afternoon appointment. After calling the doctor's office to make sure they were not running late, I arrived and waited about 20 minutes. I went to the desk and asked the office clerk how much longer I needed to wait. She said she did not know but I was next. I told her a little white lie: "I'm just wondering because I have my leftover lunch in the car that I don't want to go bad. Should I take the food home and come back?" (she didn't have to know that my lunch was in an iced lunch bag) Next thing I know, I was quickly ushered into the lab room and in and out in 15 minutes. Not sure I would tell that little lie again, but it worked that time!
