Talk to her

Apparently she learned from the last break since she starts filling glasses in preparation of the next break. You decide to that it's time to attempt to talk to her again. "So, how did you end up here?" "Erm...That's a bit of a longer story. Let's just say a friend of the owner referred me to him." "Let me guess, you went somewhere to get fucked and you were told that this is the right adress." Her shocked silence was enough to answer your question. "Then how did you end up behind the bar?" She needs a few seconds to recover and answer. "He offered me a job, I was looking for one." "I see. So are you still looking for some fun?" "I'm working!" Her blushing reveals that the outrage is fake. You move on to more casual topics, but you try to avoid personal questions to not scare her away. You're in the middle of a conversation when the next pause begins. Unfortunately she got so distracted that she barely prepared any glasses again. It only takes a few moments and a massive crowd is gathered once again.
