I did the same but with milk. My job at the time supplied coffee but not milk, the fridge was full of 1 pint bottles with names written on. There was never enough space. People got territorial over their 5sq inches of fridge. There was a milk club where they pooled together to buy milk for their group.
I couldn’t face dealing with that so opted out and drank it black. That was 15 years ago.
Some time later that employer realised they could solve a great many staff disputes for the low price of 20 pints of milk a week and started supplying it. No idea why it took so long.
My university would keep past exam papers in the library. This was apparently a little known fact, but somehow we discovered it, went and got them and use them as the basis for revision.
Turns out our professors were lazy and used the same exam every year. Does that count as cheating?
