Subaru visits a bookstore to buy a copy of a favorite book, but the employee at the register doesn't trust his motives...
If you want to buy something, 
hurry and buy it, I suppose.
Wenn du was kaufen willst, dann kauf endlich.
Si vas a comprar algo, espabila.
Ne traîne pas et achète !
Se c'è qualcosa che ti interessa, 
sbrigati a comprarla, oserei dire.
Se você deseja comprar algo, 
se apresse e compre logo, imagino.
