Colds make me stupid

I have a cold. It's not a horrible cold. I don't feel bad enough to stay home or lie in bed (not that I would get any rest if I did stay at home) but bad enough that I broke down and took some cold medicine. A little later I headed out for an errand and to pick up some lunch. I pulled thru the drive-thru, paid for my food, took the bag and then the cup and straw, and then sat there. The guy inside was busy and after a minute (or 5 or ten) he looked over and asked me what I was waiting for and I said 'my food'. He politely pointed to the sack nestled beside me. Being the super quick wit that I am, I said 'Oh' and drove away. Darn, that was my favorite drive thru and now I can never eat there again......
