I've been guilty of something similar.
Earlier last month, I went to a Cubbie day game and had to rush from Wrigley directly to my flight out of ORD in the early evening. When Soriano hit the leadoff home run, the the guy behind me jumped up to cheer and ended up spilling some beer on the back of my shirt.
I'm sure I had a few glances from people around me at the gate.
