Could you please add a button to conversations, like the Trade button for merchants, to Gareth specifically that forces the 'rent a bed' prompt? It's a bit annoying trying to force the prompt through dialogue, only for him to either gift you the key to the entire tavern, or vaguely give an option to pay gold manually and have a 50/50 of it actually registering that you get to use a guest bed. It can ruin longer dialogues too, if you ask at the end of a conversation and he just gives you the tavern key instead of a guest room.
