Medium — logic-grid deduction puzzle
Freddie, Poppy, Archie and Matilda shared a cool box on the first Monday of the fortnight, then lost the sheet that said who worked where.
It was the first Monday of the grass-court fortnight, and there were ball kids out on every court. Freddie, Poppy, Archie and Matilda shared one cool box. Each of them worked one match that day, each on a different court, and no two of their matches started at the same time. Whenever the players changed ends, each of the four grabbed a drink from the box, and each one stuck to a different drink. Two of the courts, Centre Court and No 1 Court, had a roof. The other two were open to the sky. A sheet taped to the lid said who went where, but by evening it was gone. So the four had to piece the day back together from what they remembered.
