Ruin the Tea?
Most of the stuff that passes for tea in tea-bags warrants ruining with milk or boiling water. Talking about leaves, look at any teabag you care and you'll see more dust than leaves and the leaves are so finely chopped (cut would not do justice to the process) thereby ensuring that you get a strong brew whatever you throw at it.
Personally I believe that the Reg person must have been a junior office lackey to have committed such a heinous act: pure sacrilege.
For the record the water should be 90C for tea, other temperatures between 80-95 apply for the greens & whites or reds.
