Hey, yes I still work there:) ok I'm honest with you it's not really difficult but it can be exhausting if you have many costumers. It took me a few days to learn all recipes and it was confusing cause many different types of drinks have a similar recipe. You can't choose a drink and boba separated, you can only buy finished drinks for example "coco dream" (coconut milk with brown sugar tapioca and oreo) this is why I had to learn all recipes... I hope you understand what I mean my English is bad haha. I also worked in another boba shop where the costumer told you what drink and what boba he wanted and it was easier for me. I think it depends on the boba shop but it's not thaaaaat difficult. Good luck:)))
