My phone bill was past due and I needed to change my service, so I had to visit the local Bell of Pa. office. The line wasn't clearly formed, and there was an old man with a cane nearby me. It was unclear as to who was next.
When we got to the front of the line, the man gestured to me and said, "After you."
I smiled at him and said, "No, please, after you. I have all day."
The he said, "No. You go ahead. My doctor says I have at least six months."
