Isn't that an insecticide? Oh, wait, that's DDT.....
The other day I was at a McDonald's drive-thru, and behind me was a WWII vet and his wife (I could tell he was a vet by his ball cap, and license plate). When I got to the payment window, I told the lady I'd pay for their food also. I never looked back at them, just paid, got my food and drove on. I can only imagine their surprise when they got to the window and tried to pay! I do this occasionally in many places. Sometimes I'll buy the coffee or softdrink of a person in uniform from McConnell AFB here in Wichita. Once, Sunshine and I paid for dinner for a serviceman and his family at a nice restaurant that were sitting near us. I almost always go out of my way to walk up to a soldier in uniform, or someone who I can identify as a veteran, shake their hand, and thank them for serving. It's interesting to see their replies and the smiles on their faces.
