My wife is very fastidious about her cup of tea and likes to take a handful of Tetley tea bags on holidays. She thinks that the tea one gets in the US is cr**. Not being a tea drinker, I cannot comment. But the Americans have strict rules about not allowing 'foodstuffs' and I wondered if it would be a problem if we took a SEALED packet of Tetley tea bags with us for our forthcoming 3-week visit?
