Whoa, what? You did your shift training at your old store but did no shifts running that floor before transferring? So you're running a team of strangers and don't know where anything is for your first supervisor shift? During peak?? On a SATURDAY??? Who planned this?! If there is another supervisor there overlapping with you, good lord, let them lead it so you can observe as long as possible.

If not, put yourself at DTO. You'll have a view and ear on everything without needing to know where everything is. Take someone else's advice for where to put each partner, because how would you know? Make yourself a post it note with the breaks that need to happen in he order they need to happen, and do your best to do those well. Watch everyone doing their work as much as possible, evaluate how they are doing to yourself so you can learn the dynamics. When you don't know how something is done there or where to find something you need, ASK. No good comes from trying to pretend you know things that you don't. Be prepared for them to do a bunch of stuff differently than your old store and that is fine. Don't act like your way is right and theirs is wrong.

You'll get through this, and it'll get much easier! Good luck!

Yep! Forget everything you learned at training. Keep calm and prioritise. I usually float when I run shifts so I can help wherever I'm needed. Put your strongest baristas on bar and till and don't worry too much about the floor. Don't forget to stop and breath when it gets overwhelming. Breathe and think. It's all gonna be fine. You'll make mistakes, you have to make mistakes to learn so don't panic if you do. It's just a job,not your while life. Keep that in mind. That's my 2 cents.
