Is it rude to refuse a third glass of mint tea?

It’s not rude to refuse a third glass of mint tea, though there’s a well-known saying that guests should accept three, so declining gently and with thanks is the graceful way to do it. Tea is poured generously as a sign of hospitality, and a warm "thank you, it was lovely, I’ve had plenty" is perfectly polite.

The tradition holds that the first glass is "as bitter as life," the second "as strong as love," and the third "as sweet as death," so three is the courteous number — but no host will be offended if you stop sooner. Placing your hand lightly over the glass signals you’ve had enough.

In a shop, remember that endless tea is partly a sales gesture, so you’re free to decline without obligation. In a home, accepting at least one glass matters more than finishing three; refusing the very first can seem cool.
