A cup of air-cooled joe
This is a classic case of someone forgetting to take stuff off the roof of their car after putting it there. We never really get why people do this. Can’t you just toss everything onto the passenger seat as soon as you open up the driver-side door? Well, perhaps you can’t with a cup of coffee.
The owner of this car and mug of coffee should be thankful that the steaming-hot cup of joe didn’t spray them. Also, it looks like there might still be some java left over from the trip. It might be lukewarm, but it’s better than nothing!
