My wife and ate at our favorite local restaurant last night. On our way in, a couple in front of us held the door so I could enter with my walker. The fellow acknowledged my "Vietnam Veteran" cap and thanked my for my service as I thanked them for their courtesy. We had never seen this couple before, but after our dinner, our waitress informed us there would be no bill because the other couple had paid it, but asked that we not be told until after they left! What a wonderful surprise, and one that we will certainly pass on when appropriate!
