The shop assistant asks if he can help her.

Paula agrees and says that she bought that printer a short time before,
and that she is having trouble with it already.

The shop assistant wants to know what seems to be the problem.

Paula replies that sometimes it just stops printing half way through. She adds that not every time, but frequently. She says that
it's very annoying. She says politely that she'd like a refund.

The shop assistant asks if she has a receipt.

Paula says she does and shows it (to the shop assistant).
