The Waiting Game

I refueled my car this morning, and the pumps were very slow. I arrived at work 20 minutes later than usual.

I have my annual physical this afternoon. The doctor's office left a message for me yesterday, asking me to arrive 15 minutes early. Why? I already sit there half an hour before someone calls me to be weighed. Then I sit another half hour before the doctor sees me. Do they think I need even more time to read the book I have with me?
