polish saying?

Hello,

today a polish friend of me told me that in polish there is a saying which goes like: 'i have a romance for you' . He made me believe that when you say this to someone it only means that you want to ask a favour (not specificly in romantic terms). Does anybody know more about this saying? And if it's is true that this saying exists, how do you say it in polish?

I hope that somebody knows more about this.
Thank you!!
