I have got is time but no money

I am still thinking about the gym center, even though I have decided not to take part. Main reason is it is way too expensive for me. I am not earning that much.

The sales manager was first being friendly and kind but later on she is not. She is only interested that I take part and not bother if I have got the money or not.

It is money matter and I know I must earn more before I can take part.
