Oh the Astro people.

The Astro lady called me offering a second decoder.

[...]
Astro lady: So how many tv do you have at home?
Me: Just one.
Astro lady: Oh..are you planning on adding another tv?
Me: No, not for now.
Astro lady: So here's the thing. We'd like to offer you another set of decoder that comes with bla bla bla..
Me: Ooo..kay.
Astro lady: Are you interested in the offer maam?
Me: No, I'm not.
Astro lady: And why is that?
Me: (WHICH PART OF 'I ONLY HAVE ONE TV' DOES SHE NOT UNDERSTAND?) ..err because I only have one tv!
Astro lady: Oh..ok then.

I told my brother about it and he said I should've said yes and ask her back whether the decoder could be used on our microwave, blender and such.

Troll those who don't seem to understand what you said.

Thank you.
