He has to pay

"Oh thanks." Eric says, making a grab for the trousers, but Louise suddenly backs off, pulling them away from him.

"You're not getting them for free you know." Louise tells him with a little smile. "You've got to pay for them."

Eric shrugs for a moment, but then turns, bending to pick up his trousers to grab his wallet from the pocket.

"Oh no." She tells him. "I don't want your money."

Eric looks at her confused for a moment. "Then what?" He asks.
