Last month my family traveled to San Francisco, we stopped for lunch. As we walked towards the ______ of the restaurant, a man with dirty hair, jumped up from a chair outside the restaurant and opened the door for ______. He greeted us in a friendly way.

Once inside, my daughters said softly, "Mom, he smells." We watched other customers come to the ______ but many ignored* him. Seeing this rudeness truly made me ______. I decided to set a good example to my ______. When our meal arrived, I realized I had left some medicine in the car. With the windiest trip ahead, the kids needed them, ______ I excused myself from the meal and went to get them.

Just then, the "doorman" was opening the door for a couple. They ______ past him without even acknowledging* his presence. Letting them in first, I said a ______ "thank you" to him as I went out.

When I returned, we talked a bit. He said he was not allowed inside unless* he ______ food. I went back and told my family his ______. Then I asked our waitress to add one soup and sandwich. The kids looked puzzled as we had already eaten, but when I said the order was for the "doorman", they ______.

When it was time to continue our trip, I found the "doorman" enjoying his ______. Upon seeing me, he stood up and thanked me heartily. He then ______ his hand for a handshake and I accepted. I ______ noticed the tears* in his eyes - tears of gratitude. What happened next drew great surprise: I gave the "doorman" a ______. He pulled away, with tears rolling down his face.
