# "If I give you a fiver would you give me eleven?"

Hello all,

I was watching a documentary called "Rooftop Rainforest" and there was a sentence that baffled me.

An urban ecologist asked a specialist of
tropical rainforest if she can come and rate a rooftop rainforest he will create. The specialist agreed and said she was interested to see how it comes out.
Then the
ecologist said "If I give you a fiver would you give me eleven?" And they both laughed.
What does that sentence mean?

Hello rt, if it was a British documentary, "a fiver" would be understood to mean "five pounds" (in money). In the absence of further context, I would assume they are using a rating system out of 10. One out of ten is very poor, ten out of ten is excellent. "Eleven" out of ten (it's not possible, strictly speaking) means out of this world, brilliant etc.

So he is joking by asking her if he bribes her by paying her £5, will she give him the best possible rating. Does that make sense in your context?
