Ask someone if you can do a bit of shadowing, NOT during peak! Lol
Study the recipes!!
$1As a barista who prioritizes cleanliness, take initiative and try to help clean as much as possible! My current manager would rather be strict about dress code, rather than proper cleaning, and it's incredibly annoying. Pick your battles, learn where you're crossing lines with your team.
You're team has a few vets who will help you as long as you're attentive.
And finally, it really is an incredibly fast paced job when it's busy, so be ready to be completely overwhelmed for a little bit. Good luck!
