В диалоге:
- Can I add a cup of green tea to my order?
- I am sorry, we serve only black tea.
- В таком случае не надо.

No (/without) tea then

А можно как-то без повторения слова tea?

Speaking naturally in English, you would say “in that case, I’ll have…“

... instead

Telling them to leave it off after they just told you they don’t have it doesn’t really make sense.

Or you can say something like “Oh, well that settles that.” or “Well, I guess that’s that.”
