Hogwarts School of Witchcraft and Wizardry: A Roleplay discussion

Gringotts is the only known bank of the wizarding world. It was created by the goblin Gringott. It is located in Diagon Alley and is owned and run by Goblins. In addition to storing money and valuables for wizards, one can go there to exchange Muggle money for wizarding money.

Helena walked in and asked one of the goblins," Hey, can I withdraw 100 galleons, 50 sickles, and 40 knuts." The goblin said,"Yes. Just give me your key." Helena was always creeped out by goblins voices. "Thank you. sir."
"You shall stay here, Miss. I will be right back with you're money." She waited until he came back. When he came back, Helena said,"Thanks, Sir!" And then she left.
