Supermarket tea is lacklustre at best, tea flavoured pesticides at worst.
I've had several people curse me out a bit for introducing them to good tea. Once they've had high quality tea, properly prepared, they recognise the swill used in their office for what it is.
I fully understand way people don't like tea, if their only exposure is poorly prepared ultra cheap rubbish.
