"200 mililitres - what do you think of it?"
"What do you mean what do I think of it?"
"I mean what's your opinion of 200 mililitres."
"My opinion of 200 mililitres? I don't really understand the question."
"God you're not feeling too sharp today, are you!? Out late is it!? All I'm asking is what is your opinion of 200 mililitres. Nothing more, nothing less."
"What do you mean like - of the quantity is it?"
"I can't make it any clearer."
"I suppose it's a reasonable quantity."
"There now, how hard was that?"
