It is some time after 10, so the lot is mostly empty.
The manager is walking to his car and stops to watch what passes for a breeze roll an empty beer across the lot.
There are only two cars in the lot, his old Truck and a grey SUV.
The store closed at 9 and he knew that all his employees were already home, or on their way to a darker lot to drink beer and tell lies
He walks toward the SUV and remembers that early in the day Mrs. Henderson's heart attack prevented her from finishing her shopping. The car was probably hers.
He checked the doors to make sure they were locked (they were) and picked up the can to throw it in the back of his truck.
There were others in there to keep it company.
He drove home with the windows rolled down and didn't call anyone, because there was no one to call.
