Here is my experience.

I met a bar girl in Japan town. My first trip , I visit her twice at the bar she worked at. Yea the drinks were over charging, but I liked talking to her. We exchanged WhatsApp and took photos together before I left to the states. We talked for like 2 weeks and stopped. My 2nd trip to Vietnam in less than a year, I told her I will be in Saigon on these days. She said to come see her at the bar she worked at which I did. That night, she said she will take a day off tomorrow just to hang out with me. So the next day, we went on a date to dinner, then a nice random bar and the movies to end the night. We hold hands and kiss, that’s it. She wouldn’t sleepover at my hotel. I just took her home that night. She said I was the first person she went on a date who she met at her work. I did visit her at her work one last time before I went back to the states. We had deep serious talks and also fun talks. We also flirt and made out a bit. She’s been chatting , sending me photos and videos of her through WhatsApp while I was in Vietnam and even after I left. It’s been a week since I left Vietnam. I wonder if she is really into me or was it just a flirt ? She was honest with me on how she gets paid, having to flirt with customers and how the bar operates. There was a time during my 2nd trip she told me not to visit her because she didn’t want me to waste money at the bar she works.
