The outside of the cave looks normal. Inside goes for about 10 feet til' you reach the front of the Bandit lair. Inside is a barracks and dining hall with beds and a big table with chairs around it.
Bandit Lair, Cave

I steal items and money from others. I lurk on the side of the road and prey on travelers. I harm people.
Welcome to my lair adventurer, what brings you here? Hail good sir, I appear to have gotten lost while searching for my partners. Have you seen them by any chance? Only bandits in here Ah, sorry to hear that. No one has gone by here recently then? No, we are alone Hm...I see. Perhaps I can wait for them here? I have some food I can share while we wait. Thank you kind adventurer. Usually people come in here looking for a fight.  You are most welcome sir. I see no reason for us to fight when we have only just met. Well thank you My party was supposed to be organizing to head to a nearby dungeon later today. I hope none of them have gotten lost or overslept! I can join you, I would like an honest way to bring home some food That would be excellent! We can always use someone nimble. You never know if there will be treasures or traps!
