If you're in England, it's just tea. You need to watch out for tea thieves. A tea leaf is a cockly rhyming slang for a thief. The police don't tend to arrest people for making tea wrong. It's probably not in a cup and saucer on a Wednesday morning. Definitely in a mug. An ugly mug. Just some mug. With the word muggle written on it. If you have a pug, you could have a puggle. Pug is a kind of dog.
