When you live in a place like Maryland, you forget some of the valuable winter lessons. For instance, when walking out of Panera, you can't just plop your soda on the roof of the car without first checking that there isn't enough crusty snow up there to make the surface unlevel. Second, said soda tips over and the top flies off, your first instinct may be to recover the cup and the top, not correct. You need to get to that wet lemon slice before it rests on the cold metal long enough to be fused on until the next thaw, and you find the vehicle emissions guy giving you strange looks for having citrus on your car.
I just told him I'd been having rodent problems in the garage and I figure the citric acid would dissolve them.
It didn't really help with the strange looks.
