I took 10 min using Excel.
Use 5 x 5 matrix fix teacher, John, tea.
Then do a pattern of the matrix using the other conditions. It will be like pieces of a jigsaw puzzle. Put the biggest piece in the matrix. Then the rest will be obvious.
Once you know the method, it is not so fun anymore.

Mary, the Accountant, who keeps hamsters and plays badminton, drinks coffee.
Solved in 26 minutes with the help of colorized Excel spreadsheet. Cells with same color/background indicate relationship. Text in bold indicates affirmative facts that make them unmovable.
BTW, here's how I solve it (with screenshot):
