Yes, that is why it has a notice in the Change Shop to tell you it is illegal to change money anywhere other than the Official Change Shops or the Banks.
This is why all the shops that used to (maybe still do) change money, have now taken down the signs from outside their shops, because it is illegal for them to offer to change money. Note no sign outside Zumrut's anymore. Incidentally H, he is Sedat, nice guy, we have bought from him the past, nothing against him at all, but the perhap KathB's elderly parents may not want to break the law?
