New Job as a Barista

I recently got a job at a coffee shop and I didn't realize how much there is to learn as a barista. This is my first time working at a coffee shop so I've been trying to learn the drinks and get to know what is on our menu. I found out that we have over 50 different flavors of syrups, which displays how many options for drinks there are to choose from. I am starting to learn the measurements for the drinks so I can eventually be able to make the drinks without referring to the cheat sheets. I have also learned that there are a lot of regular customers who always get the same things and I will eventually have to learn what they like.
