so my manager told me there is an opening for a supervisor shift at my store. She said if i’m interested she would train me to be a barista trainer and then i can get an interview. But i feel like i still don’t know all the little things at work. I’ve been at my store for about 9 1/2 months now and have learned very quickly. But there is a lot of stuff i feel like i still don’t know, like how to make iced coffee, which teas have caffeine, little things like that. So that’s what i’m most stressed about.
