Client: It?s even more than the last one!

Me: Yes. The contract you signed stated that I would add a late fee for payment.

Client: You mean I have to actually pay you? I thought you were joking!

Me: What on earth made you think that?

Client: You?re a freelancer!

Me: And?

Client: Well, you work for free! If you were supposed to be paid, you?d be called a paidlancer or something!
