i hope your first day went well! i'm a barista too, and i'm sure since you're trained as one already you'll find the new job much easier than if you were inexperienced. and of course everyone will like you :') i've always had that same fear too.
So I'm super nervous cuz I start my new job tomorrow. I'm a trained barista and it's a new coffee shop in my neighborhood, so it's nothing new for me but I'm nervous they won't like me >_<
Meeting new people and starting new jobs make me so anxious haha.
