That is my cup of tea (or not)

I am a tea fanatic, truth be told, was one before I lived in England.

I wanted to order peppermint tea in Spain on a visit there. My server had no idea what I was talking about. We discussed in both Spanish and English what I wanted and still, no luck. Finally the server said "do you mean peppermint infusion?".

So the source of our misunderstanding was the precise terminology, you see only the drink made from the leaves of the plant camellia sinensis (the tea plant to you and I) is actually tea, everything else is an infusion.

Sheesh, glad we cleared that up.
