Working in a bar

Hello,

I'm currently looking for a partime job on 알바천국 on top of my studies. I'm seeing a lot of offers to work in bar/모던바 around my uni. It pays better than other jobs (~20000/hour), it seems flexible and I don't mind working at night. But I don't wanna end up in a weird situation especially in the bar that include 대화 as one of their 업무. Does anyond has any experience working in bars in korea or knows if it's a reliable job ?

Thank you !
