For many of us, Christmas means a lot of time spent driving between relatives delivering Christmas cheer and indulging in one-too-many mince pies. One of the worst things about being on the road is drinking horrid machine coffee from a paper cup; I mean, I don't even consider drinking takeaway tea in those circumstances as, although I love a good cuppa, I'd rather avoid tea altogether than drink an underwhelming cup. I guess I'm just not one of those "can't live without tea types"; I find it relatively easy to give it a miss if there's only a disappointing bog-standard tea on offer.
