Just started working at a boba shop and it isn’t looking good.
Every-time I make a drink, I have an anxious feeling that the customers are waiting for a while and they will give a bad response. As a result, this makes me messes up drinks and ended up doing it again. This happened twice for me. I have remembered most of the recipe, but when they order the ones that I don’t remember or haven’t done it, I get that anxious feeling again. Can anybody help me overcome this? I know the answer might just be to remember the recipe, but even for the ones that are ingrained to my brain, I still am afraid to mess up.
