Let her play

Lana: Hmm... I guess as long as you are wining fairly it's no problem... Here, take it, but do try to win this time! Those credits were hard to come by!

Barriss: Sure thing, trust me, I am a professional! I won thousands of credits before!

Lana: Really? Are you that rich?

Barriss: Well, I was... but my luck has turned in the last game as you know...

Lana: Hope that won't be repeated...

Barriss puts your credits on the table and sits back for an other round. Her luck seems to be back, she won a round and earned 500 credits with it!

Barriss: See? Told you it was no problem!

Lana: You are really good at this game! Care to teach me one day?

Barriss: We will find time for that! But now, we could multiply this amount if I won just one more time!

Lana: Barriss, don't push your luck! Take what we have earned and move on! We have a mission, remember?

Barriss: Just one last game and we can go, I promise! You will get your share for waiting, don't worry!

She had 11 and she drew a card. It was a 10, pushing her over 20, making her the loser of the round.

Barriss: WTF! A 10 at 11...?! What were the chances of that happening...!

Lana: Great... you have just lost all that money...

Barriss: This had like 0,01 chance...! I'll prove myself next time, help me get some more credits!

Lana: Barriss! Enough! You have had your fun, don't spend any more money here! You are getting addicted to it!

Barriss: I am not! I just want to earn some extra money... Maybe if we bet our robes and...!

Lama: BARRISS! NO!

Barriss: Okay, get done with your mission, but I'll be back later, when I have some money to multiply!

Lana: Like you did this time...?

Barriss: "Ha-ha"...
