The staff were very nice. When I showed up, so did the staff from nearby stores. It turns out that all the nearby stores are owned by the same person lol. They were trying to make sales by telling you to buy more, but they were being nice about it.
I tried talking to the bartender but he either didn't speak English very well or was being taciturn. Anyway, I wish there had been more conversation while drinking and smoking weed at a bar.
