It’ll be a bit to take in as things are in different locations but it’s still a Starbucks. You make drinks, serve customers, take orders, etc. Try to socialize with the partners there if you don’t like awkward silence. Don’t worry about asking where items are as you shouldn’t be expected to know their layout. Have fun and good luck! A change of scenery is almost always nice.

It can be weird and you might feel less effective than usual. That said, I’ve taken shifts at every store in my immediate area and one thing I’ll say is in all the situations I’ve done it, expectations of you are usually reduced and if you’re coverage, shifts will probably let you do the position you want because they don’t know you and are just happy you’re there. CS is really hard at a new store bc you don’t know where anything is. So if you’re asked what you want to do, I’d pick something like bar/drive/warming where you’ll be on one station where it’s easier to figure out the layout.
